  • The weight you need should be indicated as a stamp or imprint on your old spring.
  • Measures 3/4" thick.
  • The maximum travel length is 40".
  • 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.
