Abstract
Side seal member for a loading dock seal are disclosed. An example truck loading dock seal comprising a resiliently compressible side pad supported by a relatively rigid backer and encased within a pliable cover includes at least one flexible lip protruding from the cover to seal a gap that might exist between the backer and the wall to which the backer is mounted. In some cases, the lip is part of the cover and is located where a rear vertical edge of the side pad meets the wall. The flexibility of the lip enables the lip to sealingly conform to a wall having an irregular surface. For additional sealing, a back sheet of the pliable cover includes a touch-and-hold fastener and/or overlapping layers of material that can provide a compressible seal between the wall and the backer.
