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. It's big brother is the Lomax Pro which features even stronger diamond plate aluminum panels with additional reinforcing aluminum channels than the regular Lomax cover. And it still has durable, watertight, reinforced vinyl coated hinges and automotive grade water seals. 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 whole cover only weighs around 60 pounds, yet can hold 500 pounds of evenly distributed weight on top of it. Installation available at an additional $60 charge.
