Replacement channel balance, UB 28D

A home owner from florida says:
I need to replace a few window balances but don't know which part to order. I removed the channel balance and it measures 29" end to end on the metal part. It measures 9/16? wide. It's has a label "UB 28D". I also weighed the windows and it is 23lbs each.

Thank you for posting, and for your detailed pictures! They are a huge help. However, we just need to know a bit more information before we can recommend an applicable replacement.

Please refer to the chart below and select the item that most closely matches your bottom shoe.

A home owner from florida says:
The bottom shoe does have wings and it measures 15/16". I guess that's closest to 1".

Thank you for the clarification. Judging by your 1" winged bottom shoe, I think you should take a look at our S380-29 Channel Balance. For the stamp option, I would choose 2840.
