Casement window operator

Question

I am pretty sure this is a Interlock Nova Single Arm Casement Operator. It has the "Interlock" name molded into the base. It is on my CGI casement window that was installed new in 2014. The window is hinged on the right side when looking at the window from outside.

Thanks for reaching out! Your casement operator looks a lot like our 39-458 Encore single arm operator with roller. Look over the dimensions and double check them to confirm that this is the right fit. The opposite handed versions of this operator is part 39-457.

Dimensions for 39-458

The compatible handle and cover sets for the 39-458 are the 39-375 folding set and 39-451 non-folding set.
