11/32 Spline?

A handy person from Sunnyvale, CA says:
I purchased a house from a bank that came with... well, missing some parts. I'd like to be able to open my manual skylights, but I only see splines pointing at me. As you can see, I think these can use your 11/32" universal parts, but I wanted to ask first.

That looks like 11/32", sure. If so, check out our 39-205 and 39-114L.
