Anderson Casement Window Mechanism

A home owner from Knoxville says:

I need to replace my Anderson casement window crank mechanism, which is at least 40 years old. I have attached several pics of the assembly. Please note how the crank mechanism attaches to the window.

Thank you for reaching out to us! It appears you have a Pella brand operator and an old-style Pella hinge which makes us believe this is likely a Pella brand window. The operator would be the 39-176 but I recommend you compare the specifications with your old assembly to confirm. You may also want to double-check who made your windows.

We, unfortunately, don't sell the cover for this operator so you would need to reuse your old one. I am sorry for any inconvenience.
