Contract Roller Shade System (CRS)

Section 12 24 00 Window Shades

Models

CRS-100	Manual single roller shade	One fabric band on a chain-operated clutch. The standard classroom and office shade for glare and daylight control.
CRS-200	Manual dual roller shade	Two independently operated rollers on one double bracket: a screen on the room side and a blackout on the glass side. Daylight control and full room darkening from one opening.
CRS-300	Motorized single roller shade	A tubular motor concealed inside the roller tube, with programmable upper and lower limits. Built for tall glazing, hard-to-reach openings and spaces where shades move as a group.
CRS-400	Motorized dual roller shade	Screen and blackout rollers on one double bracket, each with its own motor, so daylight control and room darkening run independently from the same wall station.
