Window crank

This window crank is an older, discontinued GU operator. To replace it, we suggest using the 39-316 Truth Dyad Operator. The opposite handed version is the 39-315. 

The compatible handles are either the 39-114L or 39-205 (folding) crank handles. These operators typically use the 39-545 and 39-546 Truth Snap-Stud Brackets to attach the link arm to the window sash. Please let me know if yours differ.

Take a look at the video tutorial below for a detailed demonstration on how to complete the installation.
