Frankenstein Shades: What Happens When a Motorized Roller Shade Is Built From Parts Made for Something Else

A roller shade is a small machine: a motor, a crown and a drive, a tube, an idler, two brackets, and on wide glass a coupler and an intermediate bracket between every pair of tubes. When those parts come from different makers, none of them designed for the others, the trade has a name for the result. Here is why a Frankenstein shade rattles, why coupled panels skip, what the makers' own installation guides require, and how we build every motorized shade from one system.

The Short Answer

What a Frankenstein shade is, and why it is never quiet for long

A Frankenstein shade is a motorized roller shade assembled from parts that were never designed for each other: a Somfy or other motor pushed into a tube from one supplier, held by brackets from a second, turning on the idler out of a manual chain-clutch kit and, on a wide opening, joined to the next shade by a coupler that was made for a different tube. Every piece "fits", in the sense that the pin drops into the slot, and the shade runs on the day it is installed. Then the tube, which a motor turns at up to 28 rpm (Somfy's figure for a Sonesse 30) every time a schedule fires, finds every bit of play in the assembly and makes it audible.

The makers say so in their own fabrication notes. Somfy's Sonesse 30 data book: "Operational noise level is reduced when motor, tube, and mechanical accessories are properly adapted" to motorized applications, and "Free play must be minimized between the accessories and the end product tube to ensure quiet performance of the motor." Crestron's coupler guide: all mounting brackets "level and on the same plane", all shades "aligned along a single axis (no off-angle positioning)". Lutron's coupled-shade guide: the coupled tubes should form "as straight a line as possible". A shade built from one system meets those lines by design; a shade built from three catalogues meets them by luck.

  • The idler: the idler of a manual clutch shade is not the idler of a motorized shade. The motor systems sell their own, usually on a bearing and matched to their own bracket; the clutch idler is a spring pin made to be turned by hand a few times a day.
  • Coupled shades: two to six tubes on one motor need the system's own intermediate bracket, with its bearing, and a coupler keyed to that tube profile. Anything else rattles at every start and stop and lets the second panel skip and drift out of line.
  • The brackets: a motor bracket and an idler bracket from one system put the tube on one centreline. Mixed brackets put the motor's axis and the idler's axis a few millimetres apart, and the fabric telescopes.
  • What doing it right costs: next to nothing against the motor. On Somfy's 2026 list an idler bearing is $0.83, a steel ball bearing for a 10 mm idler pin $3.10, an anti-vibration idler end cap holder $14.04 and a heavy-duty idler bracket $40.77; the Sonesse 30 RTS motor itself is $288.60.

We install Lutron, Somfy, Crestron and Vertilux, and we buy our roller hardware as systems built around the motor. Every quotation on this page is linked to the maker's document under Sources; the field observations are our own, from the shades we replace as much as the ones we install.

The Parts

The parts of a motorized roller shade, and who makes each one #

From the drive end to the idler end. In a system, one maker, or one fabricator building around one motor, designed every part on this list to turn on one axis with the least play. The right-hand column is what we find when nobody did.

Eight parts, two outcomes. Left to right: the part, its job, what a system supplies for it, and what we find in a shade assembled from three catalogues. The maker quotations are linked in the cells and listed under Sources.

A Somfy motor in another maker's tube is not the problem. Somfy designed for it. Its catalogue carries a crown for the Louvolite and ZMC RS Series 1 5/8 in tube, a collapsible end plug for the Louvolite System 40 and the ZMC RS Series, a take-up reel for RollEase and ZMC XL Series tubes, and adaptor plates that let a Somfy motor sit in RollEase SkyLine and R8 brackets. Those are matched parts, published by the motor maker with a part number. The Frankenstein shade is the part nobody matched: the clutch idler on the motorized tube, the bracket from the third catalogue, the coupler gripping a tube it was not cut for.

A copy of a Somfy part is a different question again, answered on original parts vs generic copies. This page is about parts that are each perfectly good, from makers that are each perfectly good, assembled into a shade none of them designed.

How It Happens

Nobody designs a Frankenstein shade. It gets built three ways #

1 · The shop

A manual-shade shop adds a motor

A fabricator with a shelf of clutch hardware, tubes, idlers and brackets for chain shades, takes an order for a motorized shade, buys a motor and builds it on the hardware it has. The clutch comes out, the motor goes in, the idler and the brackets stay. Crestron's own guide for converting its manual roller shade to a motor says what has to change: "Replace the manual clutch with the motor", and for its ARCH5 hardware, "Replace the CSA-ARCH5 manual clutch and idler bracket with new brackets." The motor is not a drop-in for the clutch. The ends of the shade change with it.

2 · The cart

The kit is bought in pieces

A motor from one online seller, a "universal" tube and bracket kit from a second, a coupler from a third. Each seller is right that its part fits a 1 1/2 in tube. None of them designed the three to share an axis, and none of them wrote the sentence Somfy puts in its installation guide: "Before installation, check that this product is compatible with the associated equipments and accessories." The same guide adds that "Any use outside the sphere of application specified by Somfy is not approved."

3 · The van

A part is substituted on site

The motorized idler was not in the van; the manual one was. It goes in "for now", the shade runs, and the installer leaves. It will be the first part to tick, because it is the only part in the assembly that was rated for a hand and is now being driven by a motor on a schedule.

The common thread is that the shade works at the hand-over. Every problem on this page is cumulative: the pin wears, the play grows, the coupler slips a little further, and the sound gets louder over months, not minutes. By the time the owner calls, the motor is usually blamed. The motor is usually the one part in the shade that was doing its job.

The Idler

A manual shade's idler is not a motorized shade's idler #

The idler is the small plastic or metal end at the far side of the tube from the motor. It looks the same in a chain shade and a motorized one. It is not asked to do the same work.

Manual clutch shade

Turned by a hand, a few times a day

You pull a chain; the clutch at the control end turns the tube a few revolutions at the speed of your hand, and the chain side takes the effort. The idler at the other end is an end plug with a spring pin that drops into a slot in the idler bracket. It carries half the weight of a light shade, slowly, and it rests between uses. A little play and a little friction cost nothing you can hear.

Motorized shade

Turned by a motor, on a schedule

The motor head is locked in the motor bracket and never turns; the tube turns around the motor on the crown and is pushed by the drive wheel. The idler is now the only other bearing point of a tube that turns at up to 28 rpm, under the full weight of the roll, on a schedule: two moves a day is more than 700 cycles a year before anyone touches a remote. It has to hold the tube's axis in line with the motor's axis, carry the load with the least friction and leave almost no end play. That is why the motor systems sell a different idler: Somfy lists nylon and steel ball bearings for its idler pins, an anti-vibration end cap holder and a heavy-duty idler bracket; ZMC's motor series lists a CM idler for each of its tube profiles, separate from the idlers of its RS, XR, XL and ST clutch lines, and a swivel ball bearing "for smooth operation of motorized shade".

Off the axis. A manual idler in a manual bracket seats the tube at that system's height and projection; the motor bracket seats the motor head at its own. A few millimetres between the two axes and the tube runs at a slight angle to the motor, against the crown, on every turn. Somfy requires the crown adapter "to ensure concentric operation of motor"; an idler on a different axis undoes the concentricity the crown provides. The fabric answers the angle by walking to one side as it rolls, which the trade calls telescoping. Lutron's guide for its manual roller says the same thing from the other direction: "excessive telescoping may result if the shade is not level", and it has the installer verify the bracket-to-bracket distance with a tape measure and the brackets level with each other before the shade goes up. Its idler pin is designed so closely to its own bracket spacing that the guide uses it as the gauge: "If the idler pin (shiny metal) is visible between the idler and idler receiver, the mounting brackets are too far apart."

Noise. A plastic pin in a plastic seat, turning under a motor's load, ticks once a revolution where it is tight and squeals where the end play lets it rub. Somfy's data book is written for exactly this: "Free play must be minimized between the accessories and the end product tube to ensure quiet performance of the motor."

End play. A spring pin has travel. Under a motor the tube uses it, shifting toward the motor as the load comes on at the start and back at the stop. The clack you hear at every start is that.

Wear. The manual idler was rated for a hand. At motor speed, on a schedule, it wears a groove in months, the play grows, and every symptom above gets louder.

Coupled Shades

Coupled shades: where mixed parts fail loudest #

On a wall wider than one piece of fabric, two to six shades share one motor through couplers (how wide one roller shade can be). The second panel has no motor of its own. It follows the first exactly as well as the coupler and the intermediate bracket let it, and everything the makers write about coupling is about one straight axis and no slack.

The rattle

Where the spindle meets the bracket

In a system, the spindle runs in a bearing. Crestron: "The retractable pin traverses the bearing in the coupler bracket, which provides support for the adjoining bands." The coupler is locked to both tubes: Lutron threads two coupler screws through the joined shafts and has the hub set screws re-tightened to 6.0 in-lbs (0.7 N·m). In a Frankenstein run the spindle sits in a plain hole, or in a bracket from another make with clearance around it. At every start, stop and reversal the slack takes up with a knock, and while the motor runs its vibration crosses the loose joint into the bracket and the pocket. A 22 ft run has two joints. You hear both.

The skip

Where the coupler meets the tube

A coupler keyed to the tube's profile cannot turn without the tube. ZMC sells a different coupler for each of its tube profiles, Lutron screws its coupler shaft through both shafts, Crestron's pin seats in detents. A generic coupler that holds a round tube by friction or two set screws slips a few degrees under load each time the motor starts. The second panel hesitates, then catches up with a jerk: the skip. After a few weeks of slipping the same way its hembar sits out of line with the first panel, which is why the systems build the levelling in (Lutron's levelling screw in each idler and its hub set screws; Crestron's ring, checked after two full cycles), and why a run with no levelling lock is a run that gets re-levelled by hand, again and again.

The bind

Where three brackets meet one axis

A coupled run is one shaft in three or more bearings. Crestron: "Ensure that all mounting brackets are level and on the same plane" and "All shades must be aligned along a single axis (no off-angle positioning)." Lutron: the coupled tubes should form "as straight a line as possible", and it has the drive shade adjusted first and each panel adjusted before the next is added. Brackets from different catalogues put the centrelines at different heights; the shaft binds in the bearings. A Sonesse ULTRA 50, which Somfy rates to drive up to six shades, has the torque to drag it through, so the run moves, loudly, with the motor working against the hardware, and the panel that is off the axis telescopes.

How many shades on one motor. Lutron: "A total of 6 panels may be coupled, including the drive shade and coupled idler panel", "subject to limitations based on drive capacity, panel sizes, and fabric selection". Crestron: up to six roller shades on one QMT motor, "depends on shade width and fabric selection". Somfy: the Sonesse ULTRA 50 has the torque "to power up up to six shades". Every one of those figures assumes the system's own hardware. A binding run spends part of that torque on friction before it lifts any fabric.

Case study.
What You Notice

What a Frankenstein shade sounds and looks like #

A shade built right makes the motor's own sound and nothing else. Anything you can hear over the motor is a part that moved.

Our Practice

How we build a motorized shade #

Our experience Six rules, in the order they come up on a job.

  1. One system per shade. The motor, the crown and drive, the tube, the idler and both brackets come from one system: the motor maker's own list for that tube (Somfy publishes its crowns, drives, tubes and brackets by tube profile), or a fabricator that builds its hardware around the motor, the way ZMC's motor series is built around Somfy's Sonesse 40 and Sonesse ULTRA 50, and the way Lutron, Crestron and Vertilux build their own. No part crosses from the clutch catalogue into a motorized shade.
  2. The idler from the motor system, on a bearing. Never the spring-pin idler of a chain shade. On anything wide, tall or heavy, the steel ball bearing and the heavy-duty idler bracket.
  3. The tube sized to the width before the motor is chosen. 1 1/2 or 2 in on ordinary windows, 2 1/2 in past about 8 ft, and the drive matched to it; the rules are on how wide one roller shade can be. A small tube on a wide window telescopes on its own, whatever the idler.
  4. Coupled runs on the system's own intermediate brackets and couplers, keyed to that tube: on a shade built on ZMC hardware, ZMC's retractable coupler with its metal spindle for that tube profile and its CM intermediate bracket; on Lutron, Lutron's coupler and sub-brackets; on Crestron, Crestron's coupler bracket. Every joint cut to land on a mullion, one straight axis set with a laser, the drive shade adjusted first and each panel as it is added, the way Lutron's guide orders it.
  5. Brackets level, in one plane, at the spacing the system gives, verified with a tape and a level before a tube goes up, which is Lutron's own sequence for its manual roller and the one we use on every shade.
  6. Run it before we leave. Two full cycles, every hembar re-checked for level (Crestron's instruction), and a listen. A quotation from us names the system the shade is built on; ask us which part comes from where and we will tell you.
Before You Sign

Four questions to ask before you buy a motorized shade #

When you invest in a motorized system you want to do it right, once. These four questions take a dealer two minutes to answer, or they do not get answered at all.

1

"Which system are the brackets, the idler and the tube from?"

The answer is a name and a parts list: Somfy LT50 brackets with the 12 mm idler bearing, ZMC's CM motor system, Lutron Sivoia QS, Crestron QMT. "Universal" is not a system, and "it's all compatible" is not an answer.

2

"Is the idler a motorized idler?"

Ask whether it turns on a bearing and whether it is the one the system lists for that motor and that tube. If the shade was priced off a manual price list with "motor" added as a line, ask what else changed at the two ends of the tube. The right answer is: the brackets and the idler.

3

"On a coupled run, what is the coupler keyed to, and how do you level the panels?"

The right answer names the tube profile and the adjustment: hub set screws, a levelling ring, a levelling screw in the idler. "We'll shim it" is the wrong answer, and so is a quote for a 16 ft wall that does not say the word coupler.

4

"Who publishes these parts?"

A dealer who can show you the maker's own page for every part is building a system. Our Somfy library lists every bracket, crown, drive, tube and idler Somfy sells, with its 2026 retail price, for exactly that reason.

Good to Know

Frankenstein shades: questions

What is a Frankenstein shade, or a Frankenstein blind? #

Trade slang for a motorized roller shade assembled from parts of different makers that were never designed for one another: a motor from one, a tube from another, brackets from a third, the idler out of a manual chain-clutch kit and, on a wide opening, a generic coupler at the join. Each part fits in the sense that the pin drops into the slot, and the shade runs on the day it is installed. The name will not appear on any quote, which is part of the problem; the way to find one is to ask which system the brackets, the idler and the coupler come from.

Is it a problem to put a Somfy motor in another brand's tube or brackets? #

Not by itself. Somfy publishes crowns, drives, end plugs and adaptor plates for RollEase, Acmeda, Louvolite, Shangri-La, ZMC and Rollerbat tubes and for RollEase SkyLine and R8 brackets, so those combinations are designed by the motor maker and carry its part numbers. ZMC builds its motor series around Somfy's Sonesse 40 and Sonesse ULTRA 50 the same way. The problem is the part nobody matched: a manual clutch idler on a motorized tube, a bracket from a third catalogue, a coupler gripping a tube profile it was not cut for. A copy of a Somfy part is a different question again, answered on our original parts vs generic copies page.

What is the difference between a manual roller shade idler and a motorized one? #

A manual idler is an end plug with a spring pin that turns in a slot at the speed of your hand, a few times a day, with the chain and clutch taking the effort. A motorized idler is the only bearing point of the tube besides the motor's crown, on a tube that turns at up to 28 rpm (a Somfy Sonesse 30), under the whole weight of the roll, on a schedule. It has to hold the tube on the motor's axis, carry the load with the least friction and leave almost no end play, so the motor systems sell their own: Somfy lists nylon and steel ball bearings for its idler pins, an anti-vibration idler end cap holder and a heavy-duty idler bracket, and ZMC lists a CM idler per tube profile in its motor series, separate from its clutch idlers, with a swivel ball bearing for smooth operation of motorized shades.

Why does my motorized roller shade click or rattle when it starts and stops? #

Almost always play somewhere between the motor and the tube, not the motor itself. A tick once per revolution is an idler pin in a seat it was not made for, or a crown packed out to a tube it was not cut for. A clack at every start and stop is end play, the tube shifting on a spring pin as the load comes on, or slack in a coupler taking up at each reversal. A buzz through the pocket is motor vibration crossing a loose joint into a bracket. Somfy's data book puts it in one line: free play must be minimized between the accessories and the tube to ensure quiet performance of the motor. We service the systems we installed; on a shade someone else built, that sentence is where its installer should start.

Why does my roller shade fabric telescope, or walk to one side? #

Three usual causes. The motor's axis and the idler's axis are not one line, which happens when the two brackets come from different systems or the idler is a manual one in a motor bracket's company; the shade is not level, which Lutron's own installation guide names, excessive telescoping may result if the shade is not level; or the tube is too small for the width and bows under the fabric. Crestron adds a rule of thumb for tall shades: keep the height within about three times the width, because a tall narrow shade rolls crooked more easily. The fix is the right tube on one axis, set level, not a wrap of tape on the roll.

What is a coupled roller shade, and how many shades can one motor drive? #

Two or more roller shades on one motor: the tubes are joined end to end with couplers that run through intermediate brackets, so the whole wall starts, stops and stays level together. Lutron couples up to six panels including the drive shade, subject to drive capacity, panel sizes and fabric; Crestron up to six on one QMT motor, depending on width and fabric; Somfy's Sonesse ULTRA 50 is rated to power up to six shades. A coupled run shows a light gap of about 1.5 in at each joint (Lutron's figure), hidden by a fascia or a pocket, and every hembar has to be set to the same height.

Why do my coupled shades end up uneven, or one panel lags behind the other? #

A coupler that is slipping on its tube. A coupler keyed to the tube profile cannot turn without the tube; a generic coupler holding a round tube by friction or two set screws slips a few degrees under load each time the motor starts, so the second panel hesitates, catches up with a jerk and, after a few weeks of slipping the same way, sits out of line with the first. The systems build the correction in, Lutron with a levelling screw in each idler and set screws in the coupler hub torqued to 6.0 in-lbs, Crestron with a ring on the idler or intermediate band locked against a hard stop and checked after two full cycles. A run with no levelling lock gets re-levelled by hand, again and again. Brackets that are not level and in one plane cause the same drift from the other side, by binding the shaft.

Can my existing manual roller shade be motorized? #

Sometimes, with the system's own motor kit. The clutch comes out, the motor goes in, and the brackets and the idler change with it, which is why Crestron's guide for converting its manual roller shade to a motor replaces the manual clutch and idler bracket with new brackets rather than only the clutch. A motor pushed into a chain shade's tube, on the chain shade's idler and brackets, is the Frankenstein build. On most homes we quote a new motorized shade on the right tube and hardware rather than a conversion; we build new shades and service the systems we installed.

Is the noise coming from the motor or from the hardware? #

Compare it with the motor's own rating. Somfy lists the Sonesse 30 at 47 dB on its current sheet and the Sonesse ULTRA 50 at 35 to 38 dB depending on the model, and its Sonesse 30 data book adds that the operational noise level is reduced when motor, tube and mechanical accessories are properly adapted to motorized applications. A shade noticeably louder than its motor's figure, or one that ticks, clacks or buzzes in time with its movement, is adding the rest in the hardware. Our ranking of the quietest roller shade motors has the published figures by brand.

How much more does it cost to build the shade from one system? #

Very little. On Somfy's 2026 retail list the idler bearing for a 12 mm shaft is $0.83, the steel ball bearing for a 10 mm idler pin $3.10, the anti-vibration idler end cap holder $14.04, the LT50 idler bracket with its nylon bearing $6.97 and the heavy-duty idler bracket $40.77, against $288.60 for the Sonesse 30 RTS motor itself. On our published price list a 72 by 84 in motorized roller shade is $833 to $2,287 depending on the system, measured, made, installed and programmed. The hardware that makes the shade quiet is a rounding error on that figure; what costs money is building the shade twice.

“I couldn’t believe how much of a change these new drapes could make! This company upgraded my apartment overlooking the water and it now has a fresh, art deco’ish vibe I can only picture in my head. The space feels modern and elegant without losing its at home feeling. From start to finish top notch work. I highly recommend them if you want your place to look like something out of a magazine.”
