Identifying Crank Park Numbers

A handy person from Penn Yan, NY says:
I need assistance identifying (2) different cranks...one right hand and one left hand side. I also need the handles for both. On the outer most arm it looks like the following letters/numbers stamped on it: OP052020. Please advise. Thank you.

Hello,

Take a look and compare the specifications of the 39-329 and 39-330 Roto operators to yours, which both use the 39-232 folding handle. Thanks for posting!

Thank you. Can you verify the if the measurements are the same as the drawing I sent? I appreciate your help.

We measure these operators a bit differently than the dimensions you've provided but as long as your part matches the specifications shown below, you should be good to go.
