Greetings,
I'm trying to locate some replacement hardware for a window. Its a bit unusual as ive never seen a casement set up this way, i actually think it might be an awning window installed sideways. What would be the best way to find a replacement crank arm assembly?
Norco hardware

Thanks for posting. Wow, you're absolutely right. This was an awning window installed sideways to make it a casement window. It looks like this might be a 39-083 or 39-140 Awning Operator, depending on the 'wingspan' of the device. See the diagrams below. Compare with your old mechanism to see what matches best. For a new crank handle see the 39-114L sold separately. Let us know if you have further questions.
