Andersen crank extension

A quick learner from Duncansville says:
I just purchased (4)of items 39-124 for a project that I am doing which I thought was going too work but they did not. Could you tell me if you have an extension like this one(same length)that fit an Anderson Window crank. Thank you

Dave Sr. from SWISCO responded:
I'm not sure what kind of Andersen operator you have, since there are many types, but most Andersen operators use a 3/8" spline. With that in mind, see our 39-442. This may fit your operator, though it is 2" long.
