SWISCO - The Replacement Hardware Authority

Casement operator

A home owner from Upstate NY says:
I need to replace two operators for my supervision casement windows. They are a truth part with the # 45035. The arm is 13.5 inches. I need both a left and right hand operator. The 39 014 and 013 look like the closet match. Is this the correct and best replacement parts even though they don't match exactly?

I agree, the 39-014 and 39-013 look like great matches. The only major difference I see is the shape of the base; ours are rounded while yours are square. This isn't an important detail, though. The manufacturer switched to the more rounded style in recent years, but it doesn't affect the function of the windows.
