Abstract
A seal for a vertically storing dock leveler employs a foam pad connected to the underside of the deck. As the leveller is lowered, the pad contacts the shelf on to which the leveller is mounted and deflects inward and compresses to seal the space between the underside of the leveller and the shelf. The pad is a tapered foam with a fabric covering.
