The Barrier Fold bi-folding cooler/freezer door from Rite-Hite uses the patent-pending Thermal Air Seal system to create a tight, conforming seal at the top of the door frame. Its efficient, high-velocity blower/defrost system broadcasts warm air evenly across the door and surrounding floor surfaces to prevent frost and reduce maintenance and operating costs.

The space-saving door comes in an internal or external freezer door-mount configuration as well as a refrigerated cooler version. It can accommodate openings ranging from 6 x 8 feet to 10 x 16 feet.

The door boasts 84-inch/second high-speed operation and one of the industry's smallest footprints, with a minimal 2-foot side clearance and projection off the wall, says the manufacturer. Superior-sealing side frames reduce conductivity with high R-value insulation. Rite-Hite Doors 800-285-5956 www.ritehite.com
