- Overlap of at least 12 in (305 mm) on all sides and top
- Valance or fascia at least 11.5 in (292 mm) wide for dual tracks
- Valance or fascia at least 12 in (305 mm) deep
- Track height above the window
- Ideally 8 to 12 in (203 to 305 mm) or more above the window head, near the ceiling, since a higher track blocks more light
- Drapery pocket minimums
- Interior height at least 12 in (305 mm)
- Interior width 7 in (178 mm) for a single track
- Interior width 11.5 in (292 mm) for dual tracks, for stack-back clearance
- Inside mount rules
- Pinch pleat preferred, because the fabric can overlap the track
- Ripplefold hangs below the track and leaves a gap
- On a ceiling, surface mount beats recess
- Stationary ends fixed to the jamb with hook-and-loop strips or double-sided tape
- Side pockets or wall overlap
- Minimum 12 in (305 mm) depth recommended along the sides of the opening
- Maximum hanger bar overlap
- Sivoia QS: 3.89 in (98.9 mm) standard bars, 8.30 in (210.9 mm) extended bars
- Alena: 3.00 in (76.0 mm) standard bars, 6.00 in (150.0 mm) extended bars
- Extended hanger bars are a custom quotation
- The drive's close limit can be set for less overlap
- Center-draw ripplefold closures
- Sivoia QS: butt closure standard, overlap hanger bars by custom request
- Alena: overlap standard, butt closure by request
- Alena master carriers need female snaps
- Drapery to floor
- Minimum 0.5 in (12 mm) clearance so the fabric hangs free, never pooling on the floor, where dragging can stop the panels overlapping
- Roller 100 versus Roller 225
- Roller 100 suits most windows
- Roller 225: panel over 15 ft (4.57 m) wide and/or 10 ft (3.05 m) tall

- Not with cable guides, battery-powered shades or shades over 5° from vertical
- No full blackout with sheer fabric

- Roller shade supply
- Roller shades ship with the fabric already on the roller
- How to judge the result
- A mock-up in actual site conditions is Lutron's method for measuring how well a window treatment blocks light
- Drapery panel weight
- Not printed: the maximum panel weight depends on the system configuration and is given on the quotation
Questions about document 048736
The answers come from Lutron document 048736 and New Way's record of it.
What is Lutron document 048736?
Lutron document 048736 is a 15-page note aiming at a 'tortured path' for light, judged by a mock-up on site.
Which revision of 048736 is current?
Rev C, dated July 2022, is the revision Lutron publishes. New Way checked it against assets.lutron.com on 16 October 2026.
Which roller shades does 048736 cover?
Lutron Sivoia QS roller shades. Lutron document 048736 refers readers to document 086106.
Which drapery configuration blocks the most light?
Lutron document 048736 prefers configuration A, a side-draw track outside the window opening, with these minimums.
- Overlap: 12 in (305 mm) on all sides and top
- Valance or fascia: 11.5 in (292 mm) wide for dual tracks, 12 in (305 mm) deep
Lutron pairs it with a pocket or fascia-mounted blackout roller shade with side channels.
When does a guestroom need Roller 225 instead of Roller 100?
Lutron document 048736 names Roller 100 for most windows. Roller 225 applies when the shade panel exceeds 15 ft (4.57 m) wide and/or 10 ft (3.05 m) tall.
Lutron warns that the Roller 225 sub-bracket and roll direction are reversed, and refers to specification documents 086106 and 086105.
How far do center-draw panels overlap?
Up to 3.89 in (98.9 mm) on a Sivoia QS center-draw pinch pleat track with standard hanger bars, per Lutron document 048736.
- Sivoia QS, extended hanger bars: 8.30 in (210.9 mm)
- Alena: 3.00 in (76.0 mm) standard, 6.00 in (150.0 mm) extended
- Extended hanger bars: custom request
The drive's close limit can be set for less overlap.
Where should the side channels of a blackout roller shade be fixed?
Lutron document 048736 aligns the side channels with the fabric drop. The drop moves toward the tube as the shade lowers and away from it as the shade rises.
The best position is found in a mock-up before fitting many rooms. Lutron warns that binding or buckling in the channels can telescope, pull out or damage the fabric.
What makes a roller shade fully blackout?
Lutron document 048736 combines a pocket or fascia mount, blackout fabric and three more parts.
- Side channels: 2.5 in (63.5 mm), with black wool pile
- Exposed hembar with black wool pile, and a sill angle
- Pocket interior painted a dark non-reflective color
Side channels do not suit cable-guided, battery-powered or over-5° shades, nor make sheer fabric blackout.
