Old windows, need parts

Question

I have an old casement window, that I need to replace both locks and cranks(left and right), the window measures 21.5", wondering if I need a 9.5" or 13.5" arm? If you could answer this I would love to get these ordered from you. Thanks

Thanks for posting! There is a good chance that we can that we can supply you with the replacement casement operator needed for your window. However, I'll need to see a photo of the entire operator to determine the best replacement. I'll need to see a photo of the body of the operator as well as the arm(s) and how the operator connects to the bottom of the swinging sash.

Your casement window lock reminds me of the 38-144 Primary Casement Sash Lock. This lock is non-handed. To confirm that this is the correct replacement, carefully look over the dimensions below. This lock is compatible with both the 38-276 and 38-277 casement sash keepers. It would be a good idea to replace the keepers along with locks, given the age of the window.
