Recessed Drapery Track

A slot the width of the track, and an end set made for the motor

TrackTrim is Blindspace's plaster-in profile for drapery tracks: an aluminum channel 90 mm wide and 30 mm deep, fixed into the ceiling framing every 200 mm while the building is open, with skim-coat flanges that let the plaster run up to a chamfered edge. The drapery track is fixed up through the profile, so there is no bracket to see, and the slot is painted with the ceiling.

What makes it different from a drywall slot is the end set. Each motorized track has a motor housing at one end and a return at the other, and Blindspace molds an end set to each: TTLMB1F and TTLRB1F for the Lutron Sivoia track, TTSMB1F and TTSRB1F for the Somfy Glydea, TTCMB1F and TTCRB1F for the Crestron track, flat ends for manual tracks. The slot ends exactly where the hardware ends. TrackTrim Click is the same profile with clips instead of screws: the track clicks in and comes out with a removal tool.

Straight runs are drawn to 30 feet on a single Lutron or Crestron motor and 46 feet on a Glydea, longer with two motors; dual tracks sit 140 or 180 mm apart; corners and curves are standard sections.

Max width here is the drawn track length. Dual spacings: 140 mm (5.51 in) on the Lutron and Somfy drawings, 180 mm (7.09 in) as the wider Somfy option. Curve radii: 250 to 508 mm (9.85 to 20 in).

On Site

What we check before the profile is ordered

Stack width against slot length

The drapery stacks below the ceiling, but the return end must clear the plaster. We size the return bracket from the system's own return and check the stack against the wall.

Motor end and power

The motor end set is at the end where power arrives: 120 V or 24 V for Glydea, the QS link for Sivoia, Cresnet for Crestron. The drawing fixes which end.

Dual spacing

A sheer and a blackout on two profiles need 140 mm between tracks on the Lutron and Somfy drawings, 180 mm on the wider Somfy layout; the corner and curve parts are matched to the spacing.

Curves and corners

A bay gets chained 22.5-degree sections at a radius the fabric can round; a corner gets a one-piece return or a curve, decided from the drapery's fullness.

Click or screw

TrackTrim Click goes in where the track may come out again for service; the clip positions are set from the stack area on the drawing.

The hairline

Fixing every 200 mm, splice pins at every joint, flanges feathered into the skim coat: the profile edge is the only line in the ceiling, and it is straight.

Good to Know

TrackTrim: frequently asked

What is TrackTrim?

A plaster-in aluminum profile, 90 mm wide and 30 mm deep, that forms a slot in the ceiling the width of a drapery track. The track is fixed up through the profile, so there are no visible brackets, and an end set molded for the specific motor and return end closes each end of the slot. After skim coat and paint, the ceiling shows a slot the color of the ceiling and the drapery hangs from it.

What is the difference between TrackTrim and TrackTrim Click?

Fixing. TrackTrim (TT1F with a screw channel, TT2F for screw-through fixing) takes the drapery track on screws through the profile. TrackTrim Click (TTC1F) takes clips, TTCL1 for Lutron and TTCS1 for Somfy, placed every 500 mm and every 100 mm where the drapery stacks, and the track clicks in without drilling; a removal tool takes it out again. Same end sets, same curves, same 90 x 30 mm section.

Which end sets fit a Lutron Sivoia drapery track?

TTLMB1F at the motor end (137 mm long) and TTLRB1F at the return end (122 mm), with TTLSRB1F as a straight return connector and TTLCRB1F as a one-piece corner for butt-jointed return ends. The fixing bracket is TTL1, or the TTCL1 clip on TrackTrim Click. Blindspace draws the Lutron track to 9,144 mm (30 feet) on one motor.

Which end sets fit a Somfy Glydea track?

TTSMB1F at the motor end, TTSIMB1F for an inverted motor, TTSRB1F at the return, TTSSRB1F as the straight return connector and TTSCRB1F for the one-piece corner, with bracket TTS1 or clip TTCS1. Blindspace draws the Glydea track to 14,000 mm (46 feet) on one motor and 21,000 mm (69 feet) with two motors.

Which end sets fit a Crestron track?

TTCMB1F at the motor end (154 mm long) and TTCRB1F at the return (108 mm), brackets TTC1 and TTC2. Blindspace draws the Crestron track to 9,144 mm (30 feet) on one motor and 18,288 mm (60 feet) with two motors.

How far apart are dual tracks?

140 mm (5.51 inches) between a sheer and a blackout track on the Lutron and Somfy drawings, and 180 mm (7.09 inches) as the wider Somfy option. The two profiles are plastered in as one slot pair, and the corner and curved sections are drawn for both spacings.

Can a recessed track turn a corner or follow a curve?

Both. The one-piece corner return ends join two straight runs at a butt joint, and the curved sections (22.5 degrees each, radii from 250 to 508 mm, 9.85 to 20 inches) are chained for bay windows and curved walls. Blindspace draws the corners for Lutron, Somfy and manual tracks, with butted and curved track options.

Does the drapery stack need more than the slot?

The slot carries the track; the stack hangs below the ceiling in the room. Where a drapery must disappear behind a wall return, the return end set is sized to the system's own return bracket so the fabric clears the plaster. We check the stack width against the slot length before the profile is ordered.
