Compression style dock seals work best with 4 to 5 inches of projection beyond the face of the dock bumper. With a truck in position, this provides 4 to 5 inches of compression creating an efficient seal. As the truck is being offloaded or loaded, the truck moves up and down causing abrasion on the seal. Optional wear pleats act as “shingles” on the dock seal. As the truck moves up and down, the wear surface is actually the wear pleat, not the direct face of the dock seal. This option is highly recommended as it prolongs the life of the dock seal.
