Crank handle replacements

Question

I need to replace three crank handles all the same size. Can someone call me to walk me through the measurements I need?

Your operator looks like a match for our 39-188, but with a shorter link arm. Yours is a little over 4" compared to our 5" hinge.

The bad news is that we don't have that size. The 39-188 may still work as-is, but you should be prepared for handiwork just in case. What you can do if it ends up not working is to adjust the position of the bracket on the sash to make up the difference. That will require drilling new holes.
