Casement Window Operators

Trying to match GU operators for a casement window. Need both left and right, 1 ech, plus crank handles. In white.
These go to a vinyl replacement.
The operator plastic housing has cracked after 20 years of service.

The closest match I find from you catalog is Truth Dyad Operator, #39-315 & #39-316.
Biggest difference I see is possibly the extension arm. My old unit is 4-7/8"hole to hole. The Truth Dyad is slightly less.
Housing is 4" wide with 3-1/8" spacing of mtg holes.

Sorry for the bad pics. As you can see, the first is the pieces of the operator and the second is the bottom of the operator housing.

Thanks for your help

Hey there!

Thank you so much for your patience during our busy season. It looks like you have an old discontinued GU operator. These aren't made anymore and the closest options we carry are the 39-315 and 39-316 operators. Take a look at the video below and see if you can use these as a substitute.
