Weather Shield casement window crank

A home owner from Las Vegas, NV says:

I need several replacement window cranks handles for my Weather Shield casement windows which were installed in 1985. The number on the handle is 45001.

If I order a part which does not work for me, what is your return policy?

Thank you,

Your handle appears to be the earlier version of our 39-114L contour shaped handle. These are used for Truth operators with the 11/32" spline. Check it out and see what you think.
