OTCO's LS-75 Dock Seals create a weather-tight closure between the loading
dock and truck, sealing out cold, rain, wind, snow, dust and fumes, while
sealing in heated or cooled air.
As the truck compresses the seal, specially formulated foam envelopes its
sides and head to attain an extra tight closure. As the truck pulls away, the
foam immediately regains its original shape.
