Hi - about to try and sell our house, but all of the window operators are old and worn down. The crank handle has the marking OP05-1509 and I think the casement operator marking is OP05-7540-03, but I need some with the hole on the right and then some with the hole on the left.
Could I get some assistance with identifying these parts?
Also, do I need any extra parts when I replace the handle and the casement operator?
