SWISCO - The Replacement Hardware Authority

ID of crank replacement

A home owner from California says:
The grooves attaching the handle to the crank have been stripped and it will no longer remain seated in the cranking mechanism. So instead of opening the window, turning the handle simply causes the cranking mechanism to come attached from the window.

As far as I can tell, the whole mechanism looks similar to your Dual Arm Crank, 16 1/8" Product Code: 39-140. The size might not be right, but the design seems to be the same.

Can you please help me ID the parts I need?

Thanks for posting, John. Just by eyeballing your operator, I think that the 39-140 might be too short. I think you may want to consider our 39-083. Compare the measurements to see if this can work as a replacement.
