I've provided three pictures of the window balances I need. I need a total of ten of them. The metal extrusion portion of the balance is 29 inches in length. I hope you are able to see both nylon pieces I need on the ends and the number on the metal is 2830.

Hello,
Take a look and compare the S370-29 channel balance with a 2830 strength option to your assembly. Thank you!
