"MILA PAT PEND" casement window operator

Thanks for contacting us. I've seen this only once or twice in the past. It seems to be somewhat uncommon, or at least it's very old. Either way, we've never been able to track down a good match for it. The design isn't similar to anything we carry.

You could consider operators like our 39-013 and 39-014, a handle like our 39-205, and a new sash-mount track like our 39-533, but there is no guarantee these will work. If they could, it may require adaptation of the sill.

I'm afraid I can't go into more detail. None of us here have any practical experience with this window. We've never come across it in person, so we haven't had the opportunity to experiment. No customer has ever gotten back to us as to whether or not this solution works, either. I'm sorry we can't offer a more confident solution.

You got it! I understand completely. Please let us know if you ever need anything else. We will do our best to help.
