The struggle with proper sealing when dealing with variable truck heights, variable door heights, sloped docks, yard jockey tilt and lift gates, resulting in water and air intrusion, is a real problem in need of a real solution.

DL Dynamic Dock Seal. A remarkable design that brings the head pad to the truck instead of the truck trying to fit to the head pad.
A simple automated cable/pulley system moves the head pad up and down to meet the secured trailer to the wall keeping out water and light thus making the Dynamic Dock Seal the premium solution for a complex problem. The up and down movement of the head pad creates a watertight seal regardless of trailer height and/or projection and without interfering with the dock door or trailer opening.
