Hello,

It looks like you could have the 39-224 Roto for a 5/16" Hex spline operator. We also offer the 39-205 crank handle for an 11/32" diameter operator spline. Take a look at both handles and see if one of them would be a good fit for your operator. Thank you!

thank you. Is 5/16 or 11/32 the diameter of the crank hole? Guessing a quick measurement will tell me.

The measurement refers to the diameter of the spline on the operator base that the handle attaches to.
