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.

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.
