Window Channel Balance - Need to ID

Question

Need help to I.D. a non-tilt window channel counter balance. I got pictures I can send. Send me an email.

One is broken, but looking to replace both to keep it the same.

Thanks.

Hello there, Jerry. I believe this is either an S380-33 or S385-33. The only difference between these two balances is the depth of the bottom nylon shoe, or the measurement from 'heel-to-toe'. See the diagram below for reference. Compare both with your old balance to see what matches best.

Comparison of the S378, S380 and S385 balance shoes.

You then have to choose a stamp option, which designates the strength of the balance. Your balance's old stamp of 32-9 is from a rating system we do not use. To know what stamp option to select, weigh the window sash that these balances support. You can then match that exact weight with one of the weight ranges listed alongside each stamp option under the product description of the balances' shop page.
