Window gear assembly

Apologies for the delay in responding, and many thanks for bearing with us. I've seen this operator a couple times, but we've never been able to find a good match. The best options we have are our 39-031 and 39-032, but you'll note that the base on ours is a lot wider than yours. You'll have to alter the sill trim in order to get these to function properly in your window. You will also have to compare our arm dimensions to yours to ensure they match. Sorry that we can't offer a closer option, and many thanks for reaching out.
