Hello, I would recommend starting by comparing the specifications of the parts that we've related on this page to yours. The 39-412 and 39-413 resemble your operator but you would need to confirm that the offset in the arm and the wheel that attaches to the sash match up to yours. Alternate image for 39-413
Alternate view of 39-413
We also offer the video below showing the best way to disengage a broken lock. Take a look and let us know if you have any other questions. Thank you! |
