5-6 years ago the right side of my casement window needed an operator replacement, and the kind ppl here were able to help me identify which part I should get to replace it.
It worked great and still does. However, now the LEFT side of my casement window needs the same procedure, but the replacement part I got from this website is no longer available. That part number was 39-415.
Can you recommend a replacement operator for part 39-415 (LEFT WINDOW WHEN LOOKING THROUGH THE WINDOW FROM THE INSIDE OF THE HOUSE). I tried part No# 39-318, but the metal part of the operator that needs to pass through the window frame is too wide for the current gap (other picture).Thank you for your help
