When you need your emergency doors to opening as fast as possible, count on the Speed-Guardian 5000. It opens at a speed of 80 inches per second; a 12’0” high door will open in four to five seconds. The compact guide tracks enable the 5000 to fit into existing building dimensions, whether in a renovation or new construction layout, as opposed to bi-folding doors which require more side room clearance and may require enlarging the overall size of the building as a result.
