Crank handle identification

Hello,

Thanks for posting! Your casement operator is an older style GU Operator. Unfortunately, it has been discontinued and is no longer available. 

The good news is that we do have a replacement solution that should work to help with replacing the existing hardware. For this project you will need the 39-316 Truth Dyad Operator; the opposite handed version is part 39-315. The compatible crank handle is the 39-114L Crank Handle.

Take a look at the video below for details on how to replace this operator.
