60" x 120" Galvanized Steel Big Smoky UL/FM Vents - Milcor

Our 60" x 120" Galvanized Steel Big Smoky UL/FM Vents - Milcor is one of the industry favourites due to its user-friendliness. This product has a heavy-duty galvanized steel cover and curbs with Torsion Coil Spring operators to open against snow or wind load. It provides convenient access to building roofs and ideal for areas that need frequent roof access. Also, this vent has a UL-listed fusible link that lets the covers automatically spring open when exposed to a minimum of 90 degrees in the event of a fire.
It features durability and a powerful load capacity with a high-strength composite construction that withstands wind uplift for class 90 roof decks. Meanwhile, its rigid foam-type and fibreboard insulation provide a barrier for any weather and protection from thermal heat. Send your orders now!
