Ideal Security’s SK929T is a pack of four T-handle window casement replacement handles that provides an obtrusive, sleek solution to seamlessly and securely operate your out-swinging window. Designed with 11/32” window operator splines in mind (slightly larger than 5/16” splines), our casement window crank handles can easily replace old or damaged window handles meeting these design specifications. With some quick adjustment using a Philips cross head screwdriver, your crank out window will be stylishly functional with our durable replacement window handle. Ideal Security has been supplying quality hardware since 1956. Please explore our other security and protection products for your home.
