Vestil Dock Seal D-350 Series — For 8 ft x 9 ft Dock Doors with Air Escape Tunnel

The Vestil Dock Seal D-350 is a heavy duty dock seal made from durable nylon-reinforced vinyl facing for an excellent seal to your truck trailer. Designed specifically for 8 ft x 9 ft dock doors, this shelter-type dock seal is made in the USA and comes with all mounting hardware, including a through-the-wall installation kit. Choose from 10 in to 20 in projections to match your dock approach.

What sets the D-350 apart from our standard D-150 series is the Full Height Air Escape Tunnel at the top of the seal — an added feature that relieves air pressure buildup during trailer compression for a more controlled, consistent seal on larger 9 ft door openings.
