Product Description
This is a Series 150 stainless steel spring for tilt windows. It moderates the operation of your window sash using a specifically calibrated coil spring that allows the window to stay open when raised and remain shut when closed.
-
Individually, this coil balance can hold 5 pounds. This is added together with the other coils to support the whole weight of the sash.
- The weight you need should be indicated as a stamp or imprint on your old spring.
- Measures 1/2" thick.
- Designed to work with the 15-140 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.
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.
