With the unique Prime-Line TH 22243 Window Operator Folding Crank Handle, you never have to worry about your shades and blinds being obstructed by the handle and not sitting flush with the window sill. Constructed of diecast zinc and extremely low-profile, the casement and awning cranks are designed to fit 11/32 inch Truth brand operator spindles and have a 2-9/64 inch reach with a 3-3/32 inch projection. It features a set screw at the base of the handle allowing it to lock onto the spindle, and a swivel knob at the tip for ease of operation, requiring far less torque than traditional low-profile handles. The unique design of the non-handed casement and awning window crank allows it to fold down when not in use. Shades, blinds, shutters and more can go straight down to the window sill without getting caught on the handle. Ideal for plantation shutters, retractable blinds and mini-blinds, the handle easily pulls out from its folded position to open or close the window. The white-enamel finish is baked on, creating a rust and corrosion resistant crank that is engineered to last. Installation is quick and easy, and all mounting hardware is included.
