Searching for 041798

Quick Learner
Our crank mechanism is stripped. I am looking for a replacement assembly. I'm sure the other side is wore out too so I'm looking for both right and left casement mechanisms.
I'm attaching some pictures so you can help me identify what I need. Thank you!

Hey there!

Thanks for your patience during this busy season of ours. Take a look at our 39-220B and 39-221B operators and carefully look over the dimensions to see if these match your original assembly.
