Open loading docks - Open loading docks are prone to damage from trucks missing the intended docking position. To prevent concrete damage a continuous extra length bumper provides the highest level of protection for your facilities loading dock.
Dock Seals and Refrigerated Warehouses - Dock seals while ideal for the sides and top of a door are prone to air flow from the bottom of the door. To properly seal the entire door an extra length dock bumper provides the ideal combination of 80% impact absorption and total coverage across the base of the door. Ask about our custom lengths.
