Hello,

I would recommend starting by comparing the specifications of the three operator pairs that we've related on this page to your assembly. The main difference is the length of the arms that attach to the sash but you'll also need to confirm that your part uses the same type of wheel at the end of the arm. Take a look and see what you think.
