The Ancra Lift-A-Deck II adjustable second deck for trailers can double amounts of palletized freight carried. The beams are mounted on tracks on the walls of the trailer and can slide up and down, including out-of-the-way when full trailer height is needed. The beams are rated to carry 2,200 pounds each and can be positioned in 1-in. increments. No track lubrication is needed, and loads can be secured with cargo straps, tie-offs and decking and shoring beams.
