The LOMAX™ Professional Series makes a bold statement with its revolutionary, low profile design and superior protection. This diamond plate tonneau cover provides a weathertight seal, simple installation and easy one person operation. To prevent elements from entering the truck box, the LOMAX™ Folding Tonneau Cover features aluminum panels with a water shedding design and water resistant hinges. Additional extruded aluminum channels increase the strength of each panel, making the hard tri-fold cover stronger with minimum added weight. The water resistant hinges, flexible rubber seals and limited metal-on-metal contact all work together to reduce noise and vibration for a quiet ride. Committed to quality and durability, the LOMAX™ Professional Series is redefining rugged.
