Spring Balances for International Window (Mfg. around 1996)

Question

The windows are 3' x 4' .  The balances fit in a channel.  The dimension of the balances is 1/2 '  x  1/2 '  x  23 '.  Each balance is stamped C2240.  About myself:  Homeowner, do-it-myselfer.  I've changed out these balances before.

Hello,

Your channel balance resembles the S770-23. Your stamp code differs from ours, but it should correspond to the 23D option for our replacements, which will support a sash between 21-24 pounds. I'd suggest weighing your sash to ensure it falls within the supported range.

If you need new pivot shoes, take a look and compare the specifications of the 15-015 to yours. Thanks for posting!
