A home owner from Rochester, NY says:
I'm looking to replace the attached crank out. Is this something you carry? Unfortunately, this is all the information I have on it.

Tom from SWISCO responded:

Your operator looks like it could be either the 39-253LB or 39-438B, depending on the design of the guide at the end of the arm. This guide is not visible in any of your photos so it is unfortunately not something I can determine for you, but the video below will go into more detail on how you can make the best pick.

We also sell the 39-451 handle/cover kit, in case you also needed that.
