Measuring the handle spline
A home owner from San Jose, CA says:

So to be sure a crank handle will fit my operator, how would I measure the spline? The spline is like a gear shape, so is it a diameter from peak to peak?

Thanks for posting!
Great question. In this case, it actually depends on the hardware manufacturer.
If you can upload a picture of your existing operator with the handle and then a picture of the handle removed, we should be able to get a better idea of what you could use as a replacement.
