This is a Titan Series 196 stainless steel spring for tilt-in 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 4-1/2 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.
Has a long tongue, meant to install on the top of a pair of coil balances. (If you have only one spring, see our Series 195 instead)
