PSI 450 Inflatable Rigid Dock Shelter

Pentalift inflatable dock seals and shelters are designed to provide an energy efficient seal accommodating a wide range of loading dock door sizes. When not in use Pentalift inflatables are kept in the deflated position increasing the life expectancy of the product. Pentalift inflatables are easily interlocked to the overhead door, vehicle restraint or dock leveler to further automate controlled environment during the loading/unloading operation. The inflatable design minimizes abrasion and eliminates pressure on the building wall often associated with a compression seal. Pentalift inflatables provide the most effective weather protected passageway between the building and the truck.
