Extension

A home owner from California says:
Hi. I want to add a 4" extension to my casement window crank. The windows were already installed when I bought my condo. There is no note of what brand they are and the HOA does not seem to have a record. Is there a universal part that would work?

Take a look at our 39-157 extension. It has a 11/32" spline and is used on Roto and Truth hardware. Could this work for you?
