407 Series 170 Coiled Balance Spring

Product Code: S170-407

Product Description
This coil spring measures 3/4" wide x 40" long, has a short tail, and is stamped with number 407 or 7. This constant force spring is used in CertainTeed double hung window sash support systems with a support weight of 7 lbs.
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.
