ACORN WINDOW BALANCES

29'' long (not including shoe or top guide)
9/16''wide 5/8'' deep
#2830

I'm pretty sure its the #19-009 top guide. Other than that I'm not sure what I need.

thanks in advance!

Thanks Paul,

I think those should work just fine. I can't wait to get these windows working right!

Just did receive my order and I have to tell you that the 15-003 bottom shoe is not a good substitute for the Acorn shoe pictured above. The problem is that the replacement shoe slips to one side or the other of the guide rails. When this happens there is too much lateral play at the bottom of the sash to smoothly close the window.

Would you have any suggestions that might help solve this problem?

Thanks, JR

They did work for me, but as mentioned there is extra lateral play in the window. For me it has worked fine for the last year. in fact I'm ordering some more right now for another window. I just make sure the window is closed with 2 hands or it is closed from the center. I could see how that would be unacceptable for some.
Other than making some from scratch or finding some old replacement parts this is the best option for me.
