Casement window control

A home owner from Cherry Hill says:
Two LH window cranks are apparently stripped and need replacement. Obviously, this photo is of the RH side that works. On the mechanism, the name WindowGard Truth and the number 20755 is stamped. Thank you.

I would start by looking at our 39-156 operator. This may be what you want, however I would make sure to carefully go over our measurements to confirm that it's the same size.
