8’0” w x 10’0” h openings

Generally designed to suit 8´ wide x 10´ high openings. The series D350 service a large variety of trailer heights. This unit minimizes pressure against the building wall from an incoming trailer as the unit is inflated after the trailer has docked. A unique internal baffle system in the vertical air bags creates a square faced design that increases the contact area against the back of the trailer. An internal retraction spring allows the header airbag to be fully retracted when not in use to prevent damage from incoming trailers.
