LOMAX<sup>®</sup> Folding Hard Cover Customer Review My Lomax cover allows for flexibility and security all in one. The tonneau cover can be easily folded up or removed to carry over-sized cargo. Also, it fits in the backseat. It is good to know that when I lock my tailgate, my truck bed is secure. But my favorite aspect of the cover is its look. It is low profile and looks great on my tuck. I am very happy with the product.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review The Lomax tri-fold cover is waterproof, folds with ease and I love that it is totally removable, if necessary. It is very lightweight and durable and folding it is so simple. I really like that the back panel locks automatically. I would highly recommend this product for anyone looking for a hard tonneau cover.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review The Lomax tri-fold cover is durable and looks great! I like how the storage straps are hidden and out of the way. The seals and hinges do a great job at keeping my truck bed dry. And this hard tonneau cover is light enough that my wife can use it.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review My new Lomax Cover adds just the right touch to my 2013 Ram pickup. The tonneau 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.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review I love the way my truck looks with my new Lomax Cover on it. If I need to haul something large, it is easy to take off. I also like knowing everything in my truck bed is protected. Overall, I am really happy with this cover and would recommend it to anyone looking for a tri-fold.

Love this cover. Easy to install, water tight, looks good and solid aluminum panels, not a styrofoam aluminum sheet.

This design and concept of this tonneau cover is unique and very impressive . Easy to install, (definitely use a couple of large spring hand clamps to hold up the rails while installing). The low profile is like no other truck bed cover out there. It adds to the looks of the truck immensely and is also totally functional for its intended purpose. We had a minor warranty issue that was handled immediately. The customer service from original sale to the warranty was tremendous. Quality of the product is excellent but yet light weight for ease of use. Thank You ACI.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review Great product easy to install (even a caveman could do it). Have not driven in the rain yet so I dont know about leaks.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review 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.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review Installed the cover yesterday on my 2019 Ram Laramie Longhorn. Fit perfect and looks great.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review Absolutely love the style and functionality and simplicity of the LOMAX hard cover. It is low-profile, tough, and can be removed from the truck and stowed in less than a minute. The diamond-plate aluminum is a very unique look and makes the truck stand out from the rest of the ordinary black covers. Love it. Installed was a piece of cake - directions are simple. Highly recommend! ACI customer service was top-notched also: Due to some business transitioning on their part, and an upcoming road-trip on my part, ACI was unable to get the tonneau cover to me in time with the standard shipping. To make up for this, they swallowed the expense of 2-day shipping (which is not cheap) in order to meet mine and their requirements. Highly recommend.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review What an awesome product! This thing is so slick. Best looking tri-fold tonneau cover on the market, hands down!

Review by: Raymond S. - OK   star star star star star

LOMAX<sup>®</sup> Folding Hard Cover Customer Review Package arrived quickly and in great shape. The parts were packaged well, so that all the parts were in perfect condition. Installation was relatively easy, although the clamps were a bit fiddly. Having a helper would have made the installation easier, but it wasn't too bad to do it by myself. The Lomax cover looks great and fits on my Chev. Silverado CC SB Z71 perfectly. It isn't perfectly water-tight against rain, but very close! I like being able to open close the tailgate without worrying about the position of the rear of the cover. I also like the ability to remove the tonneau cover completely with minimal effort.

LOMAX<sup>®</sup> Folding Hard Cover Customer Review Great cover! 200 percent better than the OEM cover for the Honda Ridgeline. Virtually no leaks! Purchased the diamond plate version. It looks and fits well. Thank you for a quality product!
