My balances are marked either 28A, 28B, or 28C after the number it is marked USB. Also I am including pix of the ends. Please suggest the proper balance. I will order 9 or 10 pair

Thanks for posting. Before we can offer an applicable replacement balance, can you please let us know the length of the metal channel portion of your balance, as well as which stamp your balance has per length? Thank you!

All balance metal channels measure 29" long. Each channel is marked either 28A, 28B, or 28C followed my the letters "USB" The width of the sash's vary from the widest at 33" to the narrow ones which are 23"w

Thank you. In that case, please take a look at our S380-29 channel balance and see what you think. For the balance with the 28A stamp, you would want the option 2810; for the balance with the 28B stamp, you would want the option 2820; and for the balance with the 28C stamp, you would want the option 2830.
