SEMCO crank handles

I have a project house built in 1978 using SEMCO awning windows and need a few crank handles. The interior spline/gear dimension appears to be 3/8" but the exterior entry to that is a bit larger like 7/16". Will this 39-104 work?

Hi there!

We'd be happy to help but we'd like to see a photo of your operator with the window open so that the arms that move the sash are fully visible. Once we can identify the operator, we can determine which handles are compatible with your assembly.

Thank you!

Client won't allow disassembly of wood trim concealing operator. Here are photo comparisons of Truth handle (in bag) and the existing, plus operator in place.

Thank you for the additional pictures! This helps a lot.

It looks like you have either our 39-083 or 39-140 operators, which use the 39-114L crank handle. We also have a folding handle, our 39-205. Both of these handles fit an 11/32" spline. Look these items over and see what you think.
