Generally designed to accommodate 10' wide by 10.5' high (3,048 mm x 3,200 mm) door openings, the HingeMaster™ is a full-access dock shelter with superior sealing efficiency. 

When barn-style trailer doors are open, the hinge gap around the sides creates the spatial equivalent of a 2 ½ square foot opening in the building wall. The HingeMaster™ J-hooks seal off this negative space, preventing debris entry and loss of conditioned air. The result is a tight top-to-bottom side seal  that does not limit access to the trailer interior.
