When you need your gear to stay safe from both thieves and the weather, the RetraxONE MX does the job. The retractable cover is built from high-quality polycarbonate (Lexan)—the same material used for jet canopies and bullet-resistant glass—and reinforced with 5/8" thick aluminum I-beams spaced every 4-3/4". It can handle up to 200 lbs of evenly distributed weight and stays strong through temperatures from -50 to 200 °F without cracking or fading. The matte black finish is scratch resistant, UV treated, and won’t show fingerprints or wear after years in the sun. Weather stripping and foam seals surround the bed, and two drain tubes route water out of the canister so moisture, snow, and dust stay out of the box.



If you haul different-sized loads, you’ll like that this cover retracts smoothly into a compact canister without needing to be removed. Sealed ball-bearing rollers glide along the rails, so you don’t have to fight straps or snaps, and the mechanism never needs lubrication. The spiral track inside the canister keeps the slats from rubbing together, preventing wear while saving space. The angled bottom of the canister leaves room for longer gear to slide underneath, and the cover can be latched partially open anywhere along the rails to protect items up front while carrying oversized cargo at the tailgate.




The pop-up handle on the driver’s side makes it easy to open or close the cover with one hand. When locked, it sits flush under a weather-guarded lid that hides the keyhole from view and keeps dirt and water out, so the lock won’t corrode or seize. Because the cover operates independently of the tailgate, you can open either one at any time. Close the cover and lock both for maximum security, or leave it partially open for quick bed access on the job or at the campsite.




The RetraxONE MX sits just 1" above the bed rails, giving a clean, near-flush appearance. Its top panel overlaps the bulkhead and canister, eliminating gaps and reducing wind drag for a quieter ride. The tough, matte black finish blends smoothly with the truck’s lines while the hard-surface design keeps the cover looking solid and modern.

Everything you need for installation is built in. The side rails attach to the canister with screws, then clamp directly onto the bed rails—no drilling required. Once aligned and secured, connect the two drain tubes through the factory holes, and the cover is ready to roll.

Evangeline Hey everyone, today we're taking a look at the RetraxONE, hard tonneau cover right here at etrailer. So this is the RetraxONE MX it's a hard tonneau cover. It's low profile. It has a canister style. It also has things like drain tubes, side rails, clamps. We'll talk about all of those different features.
And then that way, you can see what is the difference between different tonneau covers. And is this the right one for you. Especially given that I've installed a lot of tonneau covers, is I really like how sleek this one looks. It looks great. Especially here on the Nissan frontier.
It's very low profile with that canister style. It doesn't take up much room behind our window. Plus, we can see that no matter where you wanna secure it, you can secure it quickly and easily. You have those different options. The downsides though, with that latch, it's only over here.
So if I wanted to go and open it up towards the cab or over here on the passenger side that is not an option for me. I have to do everything over here. Now opening it up. I just need to push, but you would also have to reach all the way into the truck bed, to bring it back out. But that's just how it goes with tonneau covers.
It's really up to you with what type of lifestyle are you going for What are you carrying in your truck bed Do you like that this has a 200 pound weight capacity and can be locked Or is the canister taking up space inside your truck bed, a deal breaker for you So first let's talk about hard and soft tonneau covers. This is a hard tonneau cover. It has slats that slide and it can also hold up weight. In fact, it can hold up to 200 pounds of evenly distributed weight. So soft tonneau covers usually have a canvas that's stretched out over the cover. And some people aren't completely comfortable with that because what if it tears What if someone tears it intentionally With a hard tonneau cover like this you don't have to worry about that. Now the difference's between other hard tonneau covers is some are tri folding tonneau covers. Where there are three rectangles that just fold onto each other. Others are like this, where they roll into a canister. This being a canister style means, no matter what position you have this tonneau cover in, it's going to be low profile. So some others they roll up, and then they cover your rear window. Here it rolls downwards, but there is a downside to that too. A canister will take up space inside of your truck bed. And the amount of space it will take up will depend on which type of tonneau cover you get for which type of truck. So for example, we have this installed on a 2022 Nissan frontier. The size of the canister is about, nine and a half inches from the top of the tonneau cover to the bottom of the canister. Which leaves us, nine and a half inches on the bottom of our truck bed. So for your truck, if you have a fifth wheel hitch right where I am here in the middle. You can see how you can lose some space on the front, just like as if you would have a toolbox. Plus you'd have to measure for the height of the tonneau cover. So to measure for the height, we have the side rails that sit on top of our truck bed sides. But they create rails for a tonneau cover. So your tonneau cover is actually sitting half an inch below your truck bed sides. So when you consider the half inch you lose from the side rails as well as the height of your truck bed. So for example with this Nissan frontier, we are left with 19 inches of actual truck bed height space. Now let's talk about using it. Opening and closing the tonneau cover and how easy that is. So this slides, back and forth really easy. But also you can lock it into place, wherever you want. So let's say you wanna close this part of your truck bed. Bringing that latch down means you cannot push this back and forth anymore. It's locked into place. So that gives you a lot more versatility compared to some other tonneau covers where they only have the all way open or the all of the way closed position. Plus, once you have this latch down. You can then use your keys to lock the tonneau cover. So when you're ready to drive away, you close the tonneau cover. You latch it into place with the option to lock it. And then, you close your tailgate. Even with the tailgate closed, you can actually open up your tonneau cover and push this open but it will take a lot more strength. But that way if you need to grab something real quick and you don't want to have to open up your tailgate, you can do so. The downside to that is you have to access it in the back driver's side. If you wanna access it over here in the passenger side or maybe up towards the cab, you do not have that option. All of it is operated by that latch. Now the RetraxONE MX definitely is a good looking tonneau cover. It's very sleek. It's very smooth. In fact, this has been on this truck for a couple months and it still looks almost new. It's very easy to clean off. It has a high quality polycarbonate material, and that matte black finish just makes things look nice and clean. Well what if a big storm kicks up, or how does it hold up to the elements Well, even though this one's been sitting out in the E trailer parking lot for every weekday for months, it still looks really good. You can see how that UV resistance has held up. And I don't see any fading, from the finish. Now for those storms, if you do have that water come down. You also have these drain tubes included with your tonneau cover. With them installed in the canister. This thing drains that water out of your own truck's drain holes. With this being custom fit it should work with your truck's own drain holes, but it really also depends on the truck. In fact, I had to drill this one out because we had this spray in bed liner that I had to drill through. So keep that in mind when installing this tonneau cover. But this was a look at the RetraxONE MX hard tonneau cover right here, at E trailer. My name is Evangeline and I hope you enjoyed the journey..

Another year in the books, and I still believe this cover was the right choice for me. Still opens smooth and looks good. Had to replace the opening mechanism user error, but parts were readily available.

The number one reason causing trouble opening and closing the cover is either debris or misalignment. I would double check and inspect the rails for any debris and double check the alignment. Let me know if the issue does not change.
