407 Series 171 Coiled Balance Spring, Long

Product Code: S171-407

Product Description
This coil window spring measures 3/4" wide x 40" in length, has a long tail, and is stamped with number 407. This constant force balance 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.
