We feel the Access Cover Lomax aluminum folding cover is the best choice in a folding bed cover that we offer and in fact it is our best selling truck bed cover. Its sleek low profile design looks great on any truck. The Lomax features strong aluminum panels with durable, watertight, reinforced vinyl coated hinges. The panels are made from the same aluminum alloy used to make commercial trailers, and coated with a textured matte black finish to perfectly complement your trucks factory bed caps. Extruded aluminum channels on the underside of the panels keep the cover rigid while reducing weight. Flexible rubber seals, vinyl coated hinges, and limited metal on metal contact reduce noise and vibration for a quiet ride. And because this low profile cover sits on top of the truck bed rails, there are no rubber gaskets showing on the edges or drain tubes to install like other covers, yet this is the most water resistant cover we sell. Simple one person installation and removal in one minute with no tools when you need your whole bed. The complete cover only weighs around 50 pounds, yet can hold 400 pounds of evenly distributed weight on top of it. Installation available at an additional $80 charge. Other finishes like urethane coating and diamond plate are also available at a slightly higher price.
