The Smoke Fire-Tite® insulated fire shutters utilize a vinyl smoke seal on the bottom bar, brush seals on the guides and lintel to stop the movement of smoke through the door.This prevents property damage and health risks.

Smoke Fire-Tite® curtains are constructed of galvanized steel in 2 3/4″ flat, slats, and can be finished with powder coating or baked enamel finishes. All secure overhead doors are equipped with a 22 gauge steel hood formed to fit the contour of the end brackets. Durable ductile iron endlocks with 1/4″ semi-solid rivets and wind locks are available. Our door supports and brackets are all steel plates no less than 1/4″ thick. Alpine’s Torsion Counterbalance Assembly is state of the art, providing maximum security and ease of use.
