California Residents: Prop 65 Warning


Automatic Dual Locking System


Release both locks simultaneously by pulling the cord from either side. Heavy duty nylon latches provide 1/2 in. surface for solid positive engagement.

Automatic Ten Point Locking System


Unfolding each panel locks the cover automatically at ten points with heavy duty reinforced nylon components.

Tonneau Side Sealing


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.

Aluminum Channel


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.

" I spent a few months researching tri fold tonneau covers. I wanted my next one to be a hard cover, and one of my primary wishes is that it be made in the USA. Yours fit the bill and then some! I did have to wait on the install because it arrived with a broken plastic bracket but Ed came to the rescue and shipped the parts quickly. You have great staff, always willing to help, so thank you.

" This cover is beautiful and sturdy. Being old and somewhat puny (since the pandemic), I struggled a bit with the installation. The end result made it all very much worth it. "

" I am impressed with everything about this cover and company. The cover arrived quickly and packaging kept it in good shape. I was a little skeptical about the claims of easy installation. It really was a breeze to install. The coming from someone who likes to overthink everything. I am impressed with the workmanship and finish. It took a lot of looking and comparing before making a decision. I am glad I went with the LOMAX. "

" I just received and installed this cover the other day and am very impressed. The installation was very easy, it could use one more rail clamp per side, but is still really solid. It looks great too, very clean. "

" Really nice cover, super easy to install. Customer service was great....the only 2 complaints I have is #1. let customers know your company has to build these before shipping #2. invent a way to drive around with cover in open position, similar to BAK -FLIP Co. system. Otherwise , the top is great !! I also ordered the Adarack Pro Sys. Thanks to your instructions was easy to install. Note: I purchased a special router bit to auger out stake pockets. This bit made it super fast to install. You may want to consider carrying this bit yourselves. I ordered mine through BullRing in California. $10 bucks !!! Thanks Guys, love the set-up "
