Casement window crank handle

See our 39-205 folding handle. Keep in mind though it looks like your handle may have been part of a cover that had a nesting groove for the handle. If so, it probably would be wiser to replace both the handle and cover. If the spline of your operator is centered, see our 39-107FK.

There are a slew of casement operators those windows might use. If the spline on your old operators is centered, the 39-107FK might work as a replacement for both the cover and handle. Otherwise, look over the 29-205.
