Window Crank

Question

5in arm. I can't find any markings on the crank itself. The part that goes against the window is around 5 1/4in.

Hello,

It looks like the 39-221B would be our best match for your operator but there are a few differences, including the shape of the base and cover compared to the 39-375 used with this assembly. The link arm also measures 4-7/8" long as shown below. Look it over and see if this might work for your repair. Thanks for posting.
