Garden Window

Thanks for writing in! Are you looking to replace the handle on the lock or the handle on the casement window operator? We would only be able to supply you with a replacement for the entire casement lock.

Your operator is likely to be a Roto brand operator, there are a few different replacement Roto handles we can recommend. Although, I believe you can use the 39-232 for your operator. Be sure to confirm that your operator has an 11/32" spline measurement to confirm that this would be the right replacement. If not, I'll need to see a photo of the entire operator to determine the best possible replacement handle.

The plastic piece behind the lock on your window appears to be the 38-158 Roto Locking Handle Plate. To determine if this is the replacement, you'll need to carefully compare the dimensions. You'll especially want to confirm the distance between the installation holes.
