Thorne Casement Window Operator

A quick learner from Rome,GA says:
I believe I have a Thorne casement window operator for a metal frame window. It has a 9" arm and has 3 mounting screw holes. The spacing is 3 1/2" and 4 7/16". Do you have a replacement for this operator?

Thanks for posting! Please take a look at our 39-003 & 39-004 Thorn Window Cranks and compare their dimensions to your own operator to see if these can work as replacements.
