LDC D150 fixed inflatable loading dock seal

8’0” W X 8’0” H openings

Generally designed to suit 8´ wide x 8´ high openings. The Series D150 reduces pressure against the building wall unlike conventional pads while creating a tight energy saving seal against the back of the truck.

A one piece air bag construction with a unique internal baffle system creates a square faced design increasing contact area. This design ensures that off-centre trailers & even trailers that are not spotted square to the opening are sealed.
