Inflatable Dock Seal
 
Inflatable dock seals provide a tight seal for cold storage or applications requiring a high degree of sealing.  A blower inflates the diaphragm after a truck is docked and the pressure on the diaphragm acts to seal the sides and top of the truck.  This design prevents damage from incoming trailers since the unit is only inflated after the trailer has docked and deflated before the trailer departs.
