WRS Constant Force Balance Single Coils -1/2"

Stainless steel spring for tilt windows, compatible with our 31 Series Constant Force Coil Spring Balances. 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, the coil balance can hold the weight of your choice. This added together with the other coils to support the entire weight of the sash.  The weight you need should be indicated as a stamp/imprint on your old spring. This coil balance spring can work for either the left or right hand side of the window interchangeably. Coil balances are also known as Constant Force window balances.
