Need this crank to accommodate stud shoe.

I'm sorry to say that we don't sell anything like this. I've honestly never seen a configuration like this before. I would bet that this operator was the same as our 39-001 originally, but that the installers custom-fit something like our 36-078 to the end of the arm so that it would work in the window.

That is an educated guess, of course, but it looks right to me. I just don't think that would be an easy thing to replicate. The biggest issue is that we don't sell a detach clip that will fit over the 39-001 arm. If you could re-use the old detach clips then you could theoretically drill out the disc on the 39-001 and use our 36-078 in its place.

I've never done that before, though, so I cannot tell you how well it would work out. Please also understand that you would not be able to return any hardware altered in that way for a refund. In other words, it may be worth a shot but it's going to be a gamble either way.

Sure, that would be our 39-504 track. I'm just not sure if this would install the same way. This is meant to screw to the very bottom of the sash. Would you have room to do that and still have the window be operational?

Hello again! Sorry for the delay. The 39-001 arm is approximately 5/8" wide and 5/32" thick. Hopefully this size will allow you to accommodate the original detach clip.
