- Individually, this coil balance can hold 7 pounds. This is added together with the other coils to support the whole weight of the sash.
- This coil is stamped with number 407.
- Measures 3/4" thick.
- Designed to work with the 15-192 pivot shoe (sold separately).
- This coil balance spring is sold individually, not in sets.
- Can work for either the left or right side of the window interchangeably.
- Coil balances are also known as constant force window balances.
- Has a short tongue, meant to install on the bottom of a pair of coil balances or as the only coil balance in a system.
- This constant force balance is used in CertainTeed double hung windows.
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.
