I am looking to replace a casement window crank from a 1960's era Pella window. The picture is attached. Is this something you might carry?

I am afraid we don't have an exact match for this Pella operator, as it is very old. Can you give us the dimensions of the straight arm? In the time being, take a look at our 39-385 and 39-386 Egress Operators. Do you think one of these could work for you? I'm going to forward this discussion to one of our experts who specialises in casement operators to see if he has any thoughts. Many thanks.

Thank you for your patience with us. Please take a look at the split arm operators: the 39-096 and 39-176. These type have a bracket that attaches to the sash itself. See if one of these could work as a replacement on your Pella window.
