Stamped A 1/2" 3 lb Constant Force Balance Coil Spring

1/2" Constant Force Balance Coil Spring A - 3 Pound

This 1/2" constant force balance coil spring is designed for use in window sash support systems, specifically for sash weights requiring 3 pounds of counterbalance. Manufactured by Amesbury Truth Hardware, this component is a part of the Ashland® PivotTrue® Coil Balance system. It supports smooth, reliable window sash operation by maintaining consistent lifting force throughout the opening and closing cycle.

The coil is clearly stamped with an "A", indicating the weight class and compatibility. It is suitable for use as a replacement part or for assembly into new window units. The system allows for flexibility in production: you can purchase the coil spring as a standalone part or as part of a fully assembled balance kit, making it ideal for both repair and manufacturing applications.

This spring is commonly used in double-hung and other vertically operated windows that utilize constant force balance systems. Before installation, confirm that the coil matches the required weight and design specifications for your window model to ensure optimal fit and function.
