409 Series 170 Coiled Balance Spring

Product Code: S170-409

Product Description
This coil spring measures 3/4" wide x 40", has a short tongue, and is stamped with number 409. This constant force balance is used in CertainTeed double hung window sash support systems with a support weight of 9 pounds.
Good Idea!
Balances are sold individually, however, it is a good idea to replace both window balances at the same time. Pairing a new balance with an old one would cause the new balance to wear out faster.
