LOMAX™ Professional Series

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.

7 DISTINCT FEATURES
ULTRA-LOW PROFILE DESIGN
Sits less than a half inch above the truck box, the classic diamond plate finish of the LOMAX™ Professional Series Cover adds a striking appearance to your truck.
SIMPLE OPERATION
To open, pull release latch from either side and fold each panel to automatically disengage additional locks. Next, fasten with integrated storage clips. To close, unfasten storage clips and unfold panels using built-in handles. When closed, cover locks automatically at ten points, keeping cargo safe and out of sight.
WEATHERTIGHT SEAL
The water shedding design and waterproof hinges direct water away from the pickup box, no gutters or drains needed. The aluminum tri-fold tonneau overlaps the box rails with a continuous seal down the full length of the side rails, preventing elements from entering the pickup box.
STRONG YET LIGHTWEIGHT
The LOMAX™ Professional Series features additional aluminum channels under each panel. Extruded aluminum channels reinforce the panels to support up to 500 pounds of evenly dispersed weight, while weighing approximately 60 pounds for a high strength-to-weight ratio.
INTEGRATED STORAGE CLIPS
Retractable storage clips secure the truck bed cover and vinyl capped, rigid standoffs keep panels appropriately spaced in the folded position. No adjustments required.
EASY INSTALLATION
Use eight TIGHT BITE™ Clamps to install rails. Engage hooks by sliding truck cover forward and lowering into retainment brackets. Unfolding panels lock tonneau cover automatically at ten points when closed. No drilling necessary.

CUSTOMER REVIEWS
By Corey J. - ND" My new Lomax Professional Series Cover adds just the right touch to my 2013 Ram pickup. The cover is built really well. I'm confident it'll hold up to the wear and tear I put my truck through. The diamond plate looks sharp on my truck, I've already received several compliments. It's a heavy duty cover and I have no problem opening and closing it when I need to. The quality of this cover is unmatched by others I've had in the past. "

By Al A. - OH" Bought the professional series Adarac and Lomax cover and would love to give it a review for you. Wife and I installed them on our 2016 Ram and are extremely pleased with our choice. This is our play truck to to take camping and hauling our kayaks. We've gotten 5 kayaks up on it and could maybe squeeze on a 6th. The Lomax is watertight, nothing has penetrated. "
