Replacement Fire Damper Springs x2

Fire damper springs, also known as constant force springs, are essential components used on both sides of a curtain fire damper. They ensure the damper opens and closes correctly in the event of smoke or fire, helping to contain hazards within the ductwork.

Sold in pairs, as we recommend replacing both springs at the same time for balanced performance and safety compliance.
