Concealed door operator
With a floor-installed, sealed compartment for its electrical and mechanical components, the new ED400-IG Automatic Operator from Dorma Entrance Systems, Lake Bluff, Ill., is ideal for glass doors in all-glass storefronts as well as other swing door applications that demand clean aesthetics. The operator is suitable for uniquely shaped doors, such as arched, irregular or historically accurate configurations, that would be difficult to accommodate with conventional overhead automatic hardware. Compatible with new construction and retrofit applications, the ED400-IG operator features a compact 32-inch-by-6-inch-by-7-inch deep compartment that’s recessed in a weatherproof steel container and secured in the floor. The operator’s robust drive unit can accommodate doors up to 800 pounds.Dorma Entrance Systems, Lake Bluff, Ill.
