Casement window hardware & handles

Question

Hello! Could you please help me select correct replacement hardware and handles for these windows? The long arm length is 9"

Not just the arm mechanism, but what else would I need? Crank? Covers? Those metal plates that screw into the window? Can I use any screws to attach? As you can see these are pretty old and do not open windows very well. Arm constantly pops off. Cranks are all stripped.

Thanks for writing in! Your casement operator closely resembles either our 39-031 or our 39-155. To determine which of these is the correct replacement, you'll need to compare the dimensions for the arms; especially the link arm. Take a look at the diagrams below for reference.

These operators are compatible with the 39-107 cover along with the 39-114L non-folding handle, like the one you have or the folding crank handle, part 39-205. Another replacement option is the 39-107FK , which is a folding crank and handle kit.

Our 33-079 screws may work for your installation but it may be best to keep the existing screws, just in case.
