Casement window

I see what you mean. The closest operator we have to this design is our 39-031, but your link arm is almost a full inch longer than ours. I don't believe I've ever seen that before, and I haven't been able to track down such an iteration of this design.

One possible solution would be to use our 39-031, which has a shorter arm, and move the sash bracket it connects to over to make up the difference. The bracket in question should look like our 39-510. The problem with this is that it will require drilling new holes, and you need to make sure the new holes are level with the originals so that you don't accidentally hit the glass.

Would this work for you? I know it's not ideal, but we just weren't able to find your original.
