WRS Constant Force Balance Coil - 5 lbs

This stainless steel spring is designed for tilt windows to regulate the operation of the window sash. It features a specifically calibrated coil spring that enables the window to stay open when raised and securely shut when closed. Each individual coil balance can hold up to 5 pounds, which is combined with other coils to support the total weight of the sash. These coils can be used interchangeably for either the left or right side of the window. The package includes the coils only, while the housing and hardware are not included.

Constructed from durable stainless steel, the spring measures 1/2" thick and is compatible with tilt windows. It is also compatible with our 31 Series Constant Force Coil Spring Balances. The weight of the coil is stamped on it for easy identification.

For example, a 16 lb window sash with single (one coil) constant force balances will require two 8 lb coils, one for each side to match the weight of the sash. On the other hand, a 16 lb window sash with tandem (double coil) constant force balances will need four 4 lb coils, two for each side to equal the weight of the sash.
