Casement window opening hardware

A home owner from Camp Verde, AZ says:
I have two Pozzi casement windows (approximately 15" W x 37" H) that are 18-20 years old. I need to replace the hardware; one window won't open & I fear the hardware is going on the 2nd one (I hesitate to open again but may be able to if I need to measure parts of the hardware). It's more in the 'gear' portion. Not sure if any of your parts are quite correct - or if it's a combination of parts that I need. What I can read is "Truth 30744A+" & "EntryGard". The interior crank hardware seems to be fine at this time. Please advise. Thanks!

I'm not sure what you need, either. It sounds like it could be either the operator or the hinge. One could way to confirm is to disconnect the operator from the problem window and try to open and close it by hand. If it opens and closes without issue, then you just need the operator. If it still hangs up, then your hinge is the problem.

Either way, see our 39-035 and 39-036 operators, as well as the 36-048 hinge. I think these parts are just what you're looking for.
