405 Series 171 Coiled Balance Spring, Long

Product Code: S171-405

Product Description
This coil spring measures 3/4" wide x 40"; has a long tongue, and is stamped with number 405. This constant force spring is used in CertainTeed double hung window sash support systems with a support weight of 5 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.
