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