Dock Seals and Shelters Overview

Dock seals and shelters mount around the top and sides of a door opening.  They protect the loading dock area, material and dock employees from weather while a trailer is being loaded/unloaded.  They also help keep cold and hot air from escaping the warehouse (especially dock seals). Seals are made up of a wood backing topped with foam and surrounded by varying thicknesses of vinyl.  When a trailer backs up to the loading dock it presses against the seal and compresses it.  Shelters are made up of a wooden or metal frame that is covered by varying thicknesses of vinyl.  When a trailer backs up to the loading dock the trailer fits inside the shelter creating a loose cover on the tops and sides.  There is also a draft pad located on the sides and bottom of the shelter (made of the same material as the seal pads) that help stop air from flowing into the shelter from below.  Some models of seals and shelters come with an adjustable height top curtain.  Ropes (lanyards) are attached to the bottom of the curtains, run through some rings along the underside of the top curtain and then attach on the side pad or curtain to a metal cleat.  When the lanyards are removed from the cleat and pulled, the bottom of the top curtain raises to fit different trailer heights.
