Milgard saggy window problem with no adjustment ability




Hello,
Unfortunately, we do not carry your Roto casement hinges but the 36-048 Hinge Set has been used by past customers with this setup. Note that modifications such as drilling new installation holes would be required. You'll need to be careful not to drill too far into the frame since you could potentially hit the glass.
Also, keep in mind you will need to replace both the top and bottom hinges to ensure the integrity of the window's function. This set can be used for right and left-handed applications.
As for the damage to the frame, unfortunately, that is not something that we can help with. You may want to try reaching out to Milgard directly to determine if it can be repaired. Thanks for posting.
