Truth Casement Window Crank

This operator is a little weird. The link arm on yours, the one stamped with 20810, is not used on this style. That link arm is almost exclusively used on operators like our 39-031 and 39-032. I think someone might have custom adapted your operator to work with this arm, though I'm not 100% sure.

Either way, the best match we have for you is our 39-171. The link arm has a somewhat more dramatic offset then yours, so I can't guarantee that it will work, but it is the best option we have.
