Crank handle
the 39-114L handle did not work 11\32 is too small the bore on my semco handle is 7\16 any suggestions??
I agree with Casey, this looks just like an 11/32" operator. I think the issue you're having is that your old operator handle used a set-screw to install while the 39-114L is pressure fit. Give it a little more umph when you install, or maybe apply a little WD-40 first. It should snap in.
I agree with Tim and Casey, that looks like 11/32". If you're convinced it's 7/16" then you could use our 39-195, but this is very uncommon.
I would triple check your dimensions. I've seen your operator style a million times in my career here and it has always had an 11/32" spline. I actually had another customer just the other day who had something like this with the same Semco branding on the handle. They looked on the operator arms and found the name "Truth EntryGard." I would check your operator for similar stamps. Truth has only ever made operators with an 11/32" spline. That will confirm it for you. If you see no Truth marks, you could go with our 39-195.
