Perma Tech's Reducer Dock Seals provide the most effective seal possible at the loading dock door with reversed wedge cut side members, extend less foam into the door opening to effectively seal the trailer without subjecting wood backboards to damage from passing loads.
Perma Reducer Dock Seal is constructed with polyurethane foam, attached to pressure treated wood backboard through a 2″ vinyl fabric hem using screws and washers. This allows for air to be released when compressed. Brass grommets for additional air pressure release are placed in the header and bottom of side pads. The Perma Reducer Dock Seal provides the most effective seal possible at the loading dock door to ensure reduced heating and cooling costs, loading safety, security, and product protection against the elements.
