The LoMax Professional Series has a low profile design with 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 reinforced vinyl coated hinges. Additional extruded aluminum channels increase the strength of each panel, making the hard tri-fold cover stronger with minimum added weight. The vinyl coated hinges, flexible rubber seals and limited metal-on-metal contact all work together to reduce noise and vibration for a quiet ride.
