Window mechanism; Sealrite

Hello,

We can't be sure of what you need with the operator still installed, but the 39-014 would be a good place to start. If it's a match, we also offer the 39-013 opposite-handed version. Take a look and compare the 13-1/2" length and roller at the end of the arm to your assembly. Thanks for posting!
