Are "truth" style cranks this sized spline?

A quick learner says:
I need folding cranks for my Norco (JenWeld) windows so my shades clear. will the 39114L handles work?

Truth window operators are available in several different variations and sizes. You will need to remove your old crank handle and measure the gear spline on the operator to find a correct fitting crank handle.
A home owner from Queens, New York says:
hi, I am looking for a folding crank handle. the ones I have are from a manufacturer that has gone out of bussiness- Select windows. this is from the early 1980's. the opening measures 5/16" these are not folding handles. the only ID numbers that I have on the handle are it's patent numbers. which are: 1083264.

Look at the arm of the operator this handle is attaching to, if it says Truth or Wright this handle will work as well as the 39-205 folding handle. If you cannot find a manufacturer name on the operator try to identify it on our site and then look to see which handle is related. Please feel free to contact us again if you have trouble.
