Hi - I'm looking to replace a stripped casement window crank. The brand is Truth, and the numbers 20810 and L30841 are on the crank. Do you know where I could get a replacement? Thanks.

Thanks for posting. Start by looking at our 39-031 and 39-032 operators. They appear to match your hardware, but just make sure that their dimensions are the same.

Hi,

Thanks for your reply. However, the number of screws in my casement window crank plate don't appear to match those in the link you mentioned. Does this matter?

Our 39-031 and 39-032 seem to have the same screw hole placement, ours just happen to have more screw holes for different setups.
