Need to Identify and Order a Channel Balance for Non-Tilt Window

Question

Hi, I need to identify and order a channel balance for a non-tilt window.
It is 27-inches long and 1/2-inch wide.
It has these numbers stamped on it: 2630 B.S.I. M3
I've attached photos as well.
Thanks!!

Hi Chris,

You'll need the S395-27 to replace your existing balance spring. The stamp for the balance would remain the same as your 2630 stamp.

Be sure to double check the top sash guides at the top left and right corners of the window to determine if they might need to be replaced with the balances.
