Prime-Line 9 in. Aluminum Diecast, Casement Operator, Left Hand, Teardrop Type, H 3502

Restore smooth opening and closing performance to older steel-framed casement windows with the Prime-Line H 3502 Left-Hand Casement Operator. Designed as a replacement for worn or damaged window operators, this assembly helps return proper functionality to crank-out casement windows while maintaining reliable sash control. It mounts on the left side of the window when viewed from inside the home looking outward and is commonly used on older steel-framed window systems. Constructed with a durable diecast housing and crank handle, this operator features a 9 in. hardened steel arm and precision worm gear mechanism designed for long-lasting performance. The aluminum-painted finish helps provide corrosion resistance while maintaining a clean appearance that complements existing window hardware. Its robust drive system delivers smooth, controlled operation for everyday window ventilation and use. The operator installs using mounting hole patterns spaced at 3-7/8 in. and 4-3/4 in. on center, allowing compatibility with many older casement window designs. A matching diecast crank handle and installation fasteners are included for a complete replacement solution. Compare operator dimensions, mounting locations, and spindle configuration with your existing hardware before purchasing to ensure proper fit.
