Keeping your gear safe and dry doesn’t have to be a chore. The RetraxONE MX retracts smoothly with a pop-up locking handle that secures anywhere along the rails. When closed, it forms a solid barrier over your bed that deters theft and shields your cargo from the elements. The flat, hidden handle design keeps the lock protected from dirt and corrosion, while weather stripping and foam seals block out rain, dust, and snow. You can even latch it partially open to cover smaller gear while hauling long items out the back.






Built from high-grade polycarbonate (Lexan) with 5/8" thick aluminum I-beams embedded every 4-3/4", this cover is made to handle a 200 lb evenly distributed load. It performs reliably between -50?°F and 200?°F without cracking, swelling, or fading. The matte black finish is scratch-resistant and UV-stable, so it keeps its look through years of sun, snow, and road grime. On top of that, Lexan stays cooler to the touch than metal, even under summer heat.



Opening and closing the cover is quick and effortless thanks to sealed ball-bearing rollers that glide inside the rails. There are no joints, hinges, or springs to wear out, freeze, or trap dirt. The spiral track system keeps the panels from rubbing against each other, so the cover won’t bind or scratch as it retracts. It’s quiet, smooth, and needs no lubrication—just one clean motion with a single hand at the handle.

When rolled up, the cover stores inside a low-profile canister that sits at the bulkhead. Its angled bottom leaves extra room underneath for smaller gear, and two built-in drain tubes route water out through existing bed holes to keep the canister dry. The cover sits just 1" above the bed rails for a streamlined look that complements the truck’s shape while maintaining plenty of clearance for most bed accessories.


Getting it mounted is straightforward. The pre-assembled cover bolts to the clamp-on side rails—no drilling required. Once squared on the bed rails, tighten the clamps and hook up the drain tubes. You end up with a secure, low-profile retractable cover that’s ready to protect your cargo right away.

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.
