Casement Window Split Arm Operator

Question

I am looking to replace this casement Window operator. It has a single split arm. The outermost screws used to affix it to the window sill are 4.25 inches apart. The other screws into the window itself. I think I could use an operator and stud bracket together to attach it to the window. The handle end does need to be wide enough to fill the hole in the vinyl trim around the window.

Hi there!

Thanks for reaching out to us. Take a look at the 39-221B operator. This resembles the assembly shown here, but review the specifications and see if they match your repair needs.

Note that the 39-545 stud bracket is sold separately, and you can reuse your old cover and handle if it can be removed from the operator. If it can't be removed, please see the 39-451.
