Hello,

You have an older, discontinued GU window operator. To replace it, we suggest using the 39-315 Truth Dyad Operator. The opposite-handed operator is the 39-316. Take a look at the video below on how to complete the conversion. The compatible crank handles and stud brackets are also related on this page. Thanks for posting!
