Gap Sealer (GS) Series Dock Shelter


NOVA GS Series Dock Shelter—engineered for use with swing-door trailers, the GS Dock Shelter seals the air and light gaps at door hinges while still allowing full access into the trailer. This shelter provides maximum dock protection while minimizing pressure on the building wall. Utilizing foam side pads in its construction, the shelter is capable of compressing and bending out of the way of a truck that approaches the dock off-center preventing costly repairs.

Dock shelters can significantly improve the energy efficiency and environment control of buildings, reducing costs.  They provide an effective barrier against the elements, keeping loading dock dry, safe and efficient.

Dock shelters provide a positive seal between internal and external environments.  They prevent the passage of dust, insects, exhaust fumes and other airborne contaminates while the loading dock is in use.
