Dear Swisco,
Please see the photo of our casement window operator.
In order #1009528, I ordered part #39-172, but the base with the holes for fastening it to the window frame is the wrong size.
The order also included 2 parts #39-171 for other windows that need the operator replaced. The base for those is also the wrong size.
Is it possible to return these 3 parts and get ones that are the right size?
Thank you,
Peter
