Channel balance for tilt in window

Question

Hi, can you identify these parts from the pictures? It's for a channel balance for a tilt in window.

The window sash weighs 23.2 lbs.

Thanks, Chris

Hi Chris,

Your window balance reminds me of the S770-21 Balance. For the stamp, you'll need to select the 21E option. It can support sashes weighing between 22 to 26lbs.

Please let me know if you have any questions!
