The Model 640 fire-rated counter door is ideal for applications including factories, schools, concessions, hospitals, cafeterias and retail settings. Standard labels available include a 3 hour UL Class A rating for masonry applications, or a 1-1/2 hour UL Class B label for non-masonry fire walls (3 hour for non-masonry is available upon request). These doors are designed to expand upward in a fire, allowing the guides to be installed flush with the sill. Their compact, box-like form also provides an attractive finished appearance that requires minimum side-room. The 640 model door has exposed components made of primed galvanized steel.
A 1-1/2 hour UL fire-rated countertop with fire-resistant core is an available option offered in a variety of popular decorative laminate finishes. A fusible link is mounted to automatically close the door in case of fire. Additional safety and protection features are available, including: Fire Sentinel® time-delay release device, FireLite® vision lites, smoke detectors, horns and strobes.
The 640 model fire-rated counter fire door is UL approved. Factory Mutual (FM) labels are available with the addition of an FM approved flame baffle option.
Actual door color may vary from the digital representation shown here. Actual color samples are available by request through your Overhead Door Distributor.
