Milguard Casement Window parts

We have casement windows. Neither close well. One binds but does close and the other doesn't. One is missing a crank to open and close it. Three of them don't have the latch to cinch it closed. Although they do crank open and closed I don't know if the arm bent and moved it or if the wall settled. They are Milguard. On the inside it says MMS 92-6. Any help would be greatly appreciated.
Kind regards,
Marcella



Hi there Marcella.
Thank you for reaching out to us. Our first suggestion would be to give the window track a good cleaning to see if that helps. This looks like an older window so applying silicone spray to the track couldn't hurt either. I don't see the hinge pictured here but you'll want to inspect that for any damage as well.
If that doesn't help, the hardware may need to be replaced. Take a look at the 39-022 and 39-486 rear mount casement operators and 39-504 track. Review the specifications and see if any of these parts match up with yours.
Unfortunately, we can't help with the latch if it's missing. If there's an identical window with an intact one, we can use that as a reference.
