I need a new window crank for my casement window

Question

I have four identical casement windows I need new window cranks for. The current cranks are double-hinge Truth cranks, and the arms are roughly 8'' long. Also, please explain how to measure the crank length so I can order the correct one.

Thanks for reaching out! Your casement operator looks like an older version of our 39-171, its opposite handed version is part 39-172. Look over the dimensions and compare them to your existing operator to confirm that this is the right fit.

Dimensions for 39-171

The compatible crank handle is part 39-114L. There is also the 39-205 which is a folding handle.
