Pella casement crank with a 6-1/4" arm length

A professional from Menlo park says:
Need to replace crank very similar to what your site shows but the arm length on the sash is 6 1/4" long. Do you have that? Ss

I am sorry, I do not know which crank you are looking at. Can you provide a SWISCO part number of the crank that looks similar to yours? If your crank is not exactly the same as the SWISCO crank you are looking at, please submit a photo of your existing crank.

Are there any names or numbers printed on your old crank?

Take a look at the 39-175 and 39-176. I think this style operator is the replacement you are looking for. Here is the measurement of the arm of the 39-175 operator.
