Replacement channel balances 26.5"

A home owner from Lake Worth Florida says:
I have 2 broken channel balances that do not have a stamped part number on them. The windows were installed in 1998 by the home builder. They are builder grade, aluminum framed windows.
The metal part of the balances are 26.5 inches long with black couplings. The window is non-tilt, single hung.

Thank you for posting! Unfortunately, I'm having a difficult time making out what the stamp in the bottom picture says. Can you please confirm?

Also, can you please refer to the following chart and pick out your bottom shoe from the examples provided? This will help us determine your balance series.

A home owner from Lake Worth, Florida says:
The bottom picture, stamped in ink, reads:

UNIQUE 26.5-D-40

These "bottom shoes" don't resemble anything that fell out of my window.

The metal part is 1/2" X 5/8"

Thanks for the information. Your shoe actually does resemble our shoes, except yours appears to be black. I see that it doesn't have wings, so the replacement would have to either be 15-001 or 15-002. What is its width? Is it an even 1", or 1-1/8"?
A home owner from Lake Worth, Florida says:
The width of my shoe is an even 1".

After looking at it closer(now that I know what I'm looking at, a shoe)it looks similar to 15-002.

A home owner from Lake Worth, Florida says:
My channel balances are Series 351.

They are available in 26" or 27" lenghts.

The metal piece on mine are 26.5".

The metal parts are fine as well as the top pieces and shoes, some of the pulleys are broken, one of the rivets is broken and one of the springs broke.
