Fusible Links

Fire Damper Springs or Constant Force Springs are used on both sides of a curtain fire damper helping to shut and open to stop smoke or fire in the ductwork.

These are sold in pairs (as we recommend that both are changed at the same time).

We offer a large range of replacement fusible links which can be used in different ways in dampers, doors and vents. All of the common fusible links are in stock and for sale on this page - please enquire for other types if you cannot find them on our website.

Common fire damper makes these are used on are: BSB, HVC, NCA, Advanced Air & Action Air (Swegon) Chubb Fire, Flaktwoods, A1 Shutters, Lindab Fire Dampers, Wolseley UK, Ascot Doors, Kidde Thorne & Gilberts.
