Looking for a replacement for a number of operators in my old cabin. let me know if you have any questions, please.

Picture 2250: Distance from Main lift arm operator body hinge pin to articulating small arm braded pivot = 2 5/8"

Picture 2252- overall center/center of small arm pivot hole = 2 1/8". There is a 3/8" Dia pin hole where it " Eclips" to window frame

Picture 2254- Hole to hole on main body securing screw holes= 5 1/8"

Picture 2256- Hole to hole on main body extension foot= 7/8"

Picture 2257 - subject piece overview- my problem is the retaining ring has popped out of most and the drive screw is corroded.

We unfortunately don't sell this exact operator. Among all the products we have, I would say our two closest options are the 39-278 and 39-252. Neither one is exact, though, and I'm not sure if either will be fully compatible.

All the same, they are at least worth considering. Review their specs and see what you think.
