Extreme® 300 Series High Performance Grille

For building owners and maintenance managers tired of repairing or replacing commercial doors or security grilles, the Extreme® 300 Series High Performance Grille is the answer. Ideal for parking garages, airports and transportation hubs or other high traffic openings, the 300 Series High Performance Rolling Grille operates up to 3 times faster than standard overhead coiling grilles and is engineered for 300,000 open and close cycles. If you need a high speed grille, the 300 high performance grille has fast opening speeds of up to 24″ per second and closing at 12″ per second, which maximizes productivity, smooths traffic flow and reduces downtime in high traffic applications.
