Easy to use no pull strings! Simply pull the Soft Ascent SideVisor down to any setting. To retract the visor, pull down and the visor gently retracts into a painted black aluminum case. Now the driver can lower and raise the visor with one hand while driving! 100% opaque fabric on the top 18" and 100% visibility solar screen on the bottom 18". 36" drop for maximum shade. Installation tips: Soft Ascent SideVisor width specifies total overall width of the visor. Requires a flat, unobstructed installation area that is a minimum of 2" high, 2" deep, and as wide as the overall width of the shade being ordered. Roller brackets may be mounted to wall or overhead.
