Where safety and fire protection are crucial, choose our Fire-Rated Rolling Door. This doors are the standard for facilities that require a listed fire door in a rated fire wall. The doors are provided with fusible links that automatically release to close the door at 165oF (73oC). The door's descent can also be triggered by smoke and heat detectors, a building's alarm system, or SS90 fail-safe release devices. Fire-Rated Rolling Doors are C-UL and CSFM-labeled.
This full-featured, competitively priced product is designed to exceed industry guidelines with a UL four-hour rating.

FIRE-RATED ROLLING DOOR FEATURES
1) Fusible links.
Automatic door closure is initiated by one of three fusible links that melt at 165o Fahrenheit (73oC).
2) Spring-loaded governor.
Incorporates corrosion-resistant components to assure a smooth, controlled descent. Protected by a steel head plate cover.
3) Counterbalance system.
A torsion-spring-operated system, enclosed in a structural steel barrel, effectively counterbalances the door for a minimum 7,500 cycles.
4) Curtain.
All Fire-Rated Rolling Door curtains are constructed with heavy-duty steel slats.
5) Bottom bar.
Curtain bottoms are reinforced with a minimum of two steel angles for maximum durability. A bottom astragal is included on all motor-operated doors.
6) Guides and end locks.
Structural steel angle guides provide added support for curtain slats. Zinc-plated, malleable cast-iron end locks prevent lateral movement of the curtain slats.
7) Curtain hood.
For maximum structural rigidity, curtain hoods feature rolled edges and are formed from 24-gauge, hot-dipped galvanized steel.*
* Fire-Rated Rolling Door hoods include a flame baffle that is activated by a fusible link.
