7.5 lbs Series 160 Coil Balance

Product Code: S160-7

Product Description
This is a Series 160 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 7-1/2 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 a 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.
