As suggested by your help line, I am emailing the order information from a recent order and a photo of the channel balances they were meant to replace. The shoes are too thick to allow the window to close. Can you determine what should have been ordered?
Did the markings on the picture tell you anything about the type of balances I had? It might be the 380 I need, but I measured the gap on a matching window that seems to be working, and each shows about 3/4 of an inch in the channel to the inside edge of the frame. Your shoes are 1 3/32 and 1 inch respectively. Are those too big for my window? I didn't see a unit with a 3/4 inch shoe.
Please let me know what you recommend.
Mike
