Thanks for posting, Phil. Take a look at the 36-021 four bar hinge assembly. This looks like it might be the type you have. See if you can match up the length and width of your existing hinge to our specs. Another possible option is the 36-004-10 hinge. This is the type of hinge that is normally used on casement windows; if your window isn't particularly large or heavy then this might be a better choice. The 26-021 is a 4-bar assembly typically only used on heavy duty applications.

Detail of 36-021

There are a few different possibilities depending on the method by which your operator installs, which I can't quite make out. The two main options I'm thinking of are our 39-022, which uses rear-mount screws, and the 39-142, which uses face-mount screws. Look them over to determine the best option.

Please also note that they have 11" long arms, measuring from the center of the wheel to the center of the gear. You should measure your original to ensure that it's the same size.

Hello again! This appears to be the same window you were asking about before. My colleague Dave made several recommendations above. If you haven't already, I highly recommend reviewing these products in our catalog. We have detailed information and diagrams for each product that you can use as a reference.
