10’0” w x 10’0” h openings

Generally designed to suit 10’ wide x 10’ high openings. The series D450 service a large variety of trailer heights. This unit allows full access to the rear of the trailer when loading and unloading. An internal oil tempered spring on the header air bag and counter weight retraction design on the vertical bags allows the top and side air bags to fully retract when not in use. This design prevents damage from incoming trailers since the unit is inflated after the trailer has docked and deflated before trailer departs.
