Milgard window not closing fully
Hi Dan,
Thanks for your post! It sounds like your window operator might be stripped. It is a match for the 39-091 ROTO Casement Operator. I'm confident this should be the replacement you need but be sure to look over the dimensions.
You'll need to reuse the link arm for the installation.
If the operator is in good working condition, then the next thing to examine will be the window hinge. Yours reminds me of the 36-031 Pivot Hinge Set. This set can be used to replace top and bottom hinges, for right and left handed applications.
My pleasure to assist! Please don't hesitate to reach out with any other hardware repair questions you might have.
