Replacement two arm operator needed

Question

Hello, I have Truth windows made in 2001 and need to replace several operators. I am trying to identify which operator I have.

Thank you.

Thanks for posting. This looks like either the 39-253LB and 39-253RB dual-arm operators, or the 39-438B and 39-439B set. These two pairs are identical except for the appendage at the end of the straight arm. The video below explains more. For either pair, you can use the 39-375 and 39-376 or the 39-451 and 39-452 as new cover and handle kits. Let me know if you have further questions.
