Features to know about

Haul More Gear: Built-In T-Slot Rails

With the RetraxPRO XR, you can carry bikes, kayaks, or ladders above your bed while keeping the rest of your cargo secure underneath. The built-in T-slots along the side rails let you add compatible racks from Thule, Yakima, or Rhino Rack without affecting how the cover operates. You can open or close the retractable aluminum panels just like normal, giving you full flexibility for work or adventure setups.

Smooth Access Every Time: Sealed Ball-Bearing Rollers

Many retractable covers can bind, wear out, or require constant lubrication. This one glides open and closed on sealed ball-bearing rollers that don’t need greasing and won’t jam with dirt or debris. The cover slides easily with a pop-up handle that lets you guide it with one hand from either side of the bed. When you’re done, it retracts into a compact canister that leaves more space for cargo thanks to its angled bottom design.

Keep Valuables Safe: Lockable Aluminum Slats

When you close and lock this cover, your gear stays protected behind solid 1" thick aluminum panels. The locking handle sits flat and concealed under a lid to deter tampering and guard against corrosion. You can latch the cover anywhere along the rails—handy when you’re hauling long items while still keeping smaller gear hidden and secure near the bulkhead. Combined with your locked tailgate, it creates a tough barrier against theft and weather.

All-Weather Defense: Sealed Construction with Drain Tubes

Rain, snow, and dust stay out thanks to weather stripping and foam seals that line every edge of the cover. The top panel overlaps the tailgate to block water from seeping in. Any moisture that does reach the canister drains through two included tubes routed through the bed’s factory holes, keeping the stored cover dry and clean. It’s built for all-season use—no worries about corrosion, freezing hinges, or trapped debris.

Strong and Sleek: Heavy-Duty Matte Aluminum Build

This retractable tonneau isn’t just about looks—it’s built to last. The 1" thick aluminum slats support up to 500 lbs of evenly distributed weight and can handle heavy snow loads or impacts without bending. The matte black finish resists scratches and fading so it stays sharp year after year. With side rails sitting just 1" above the bed, it keeps a low-profile appearance that complements your truck while adding serious function.

Video Transcript for Complete Breakdown of the RetraxPRO XR Hard Tonneau Cover

Hi, Matt here with etrailer and today we're gonna be taking a look at the RetraxPro XR line of hard tonneau covers. You want to use our fit guide here in etrailer to make sure you're getting the right fit for your truck. Now this is gonna be a great option for you if you're looking for something that's gonna help keep the things in the back of your bed protected from the elements or if you wanna save one some extra gas and you want something that's gonna be custom fit. So let's check it out. So the tonneau cover we're gonna have today is gonna be retractable canister style. So what that means is it's just gonna roll up into itself and save you on a lot of space.

We're also gonna have an aluminum construction with a matte black finish to it. And what's nice about that aluminum construction is it's gonna be very durable and strong as compared to if you had any soft covers. If you had a soft covered tonneau cover, then someone could come by, just cut it open and access whatever you had in your bed. In our case today, this is gonna have the ability to lock so no one will be able to open up your tonneau cover. And if you have a locking tailgate like we do, then no one will be able to access any of it.

But let's open up so we can take a closer look at it. So to do that we're gonna have this box right here. This is gonna have a door on top of it. When you remove that door, you'll notice we have that lock core. That's what I was talking about earlier about this being able to lock.

And with it in the unlocked position, you can just press this button, it's gonna release your tonneau cover, and you'll have the ability to slide this back. Now in some cases, if you don't want to pull it all the way back, you just wanna pull it some, you would actually close this back down until it clicks into place and it'll lock it in this position. The reason why you might want that is you might have something that you want to access a lot. Something like if you had to tote right here, try to get some tools out of here, but you have other items in the back that you don't want getting wet or being out in the elements. And the way that this rolls is pretty smooth.

We're gonna have some ball bearings that go along this track on the inside that just slide right down until it goes all the way back to the canister. And what I also do like about this is we don't have any hinges or anything like that that can get gunked up over time or get damaged. So since this just rolls into place, you don't have to worry about a lot of extra things breaking. Continuing on with the rails, they're gonna sit up just about an inch on the back of our bed, which isn't bad at all. It's actually pretty low profile for how like robust and sturdy they are. And something that really sets it apart is that we're gonna have this T channel that runs through either the side of our rails. So what that T channel's gonna allow you to do is mount up any accessories or if you wanna put anything up like ladder racks or bed racks and you still want to use your tonneau cover, you're gonna have that ability and it's still gonna be compatible with a lot of our more popular brands on our website. You probably noticed when we're opening up our tonneau cover, we have this 5th wheel back here. That might be a concern of you if you have anything like that back here. And the total height that the 5th wheel we have today is gonna be a little bit less than 20 inches and we still have clearance to open up our tonneau cover. Now let's check out our canister. So like I was talking about earlier, what's nice about this is it doesn't take up a lot of room up behind our cab, so it's not blocking anything, but it is gonna take up a little bit of room in your bed. So we get some measurements. The first measurement I'm gonna get is gonna be the total length it adds, and that's gonna be about 13-1/2 inches in your bed. So the bed we have today is about 6-3/4 feet long. So you're gonna lose about a foot. Now the feature of the canister is it's gonna have a spiral design. So what that means is the way it rolls up into itself is it's not gonna making contact the entire time. So you don't have to worry about it rubbing against itself, making some wear and tear over time. And at the bottom we're gonna have some drain holes. You'll notice we'll have a tube that runs down. You're gonna have two of those in total. So the reason why we want to have drain tubes on our tonneau cover is because it's gonna prevent any water from pooling up inside and provide that water to run through so we don't have any rusting from occurring. Another thing that's gonna keep water out of here is gonna be our weather strips. We're gonna have one on the back of our canister so you don't have to worry about any water coming into your bed. Another area we're gonna have a weather strip is gonna be on our rails right underneath here, so you don't have to worry about water pooling up underneath them either. What's also really nice is this isn't gonna require any drilling for at least mounting it onto your vehicle. We're gonna be using these clamps. There's gonna be four in total, but it's just gonna grab on to these rails and your bed rails and secure it into place. But when you're ready to go, roll this out, just make sure it's unlocked and just pull it out. It shouldn't be very hard if you measured everything right and just make sure to lock it back up so it doesn't roll out on you. Overall, I think it's gonna be a great option for you if you are looking for something that's gonna be very secure where people won't be able to access underneath it and you're looking for something robust, sturdy, it's gonna have a clean finish to it too. And the fact that it's able to work with ladder racks and bed racks up to 500 pounds, it's gonna be great because you'll be able to load this up with a lot of items. If you are doing that, just make sure you check what your vehicle is capable of hauling. You can find that in your owner's manual. And your ladder racks and bed racks just make sure you know how much that can handle too. And that completes our look at the RetraxPro XR line of hard tonneau covers. Thanks for watching.

by:

We purchased these to allow us to mount the rails to carry our bikes. So far, that’s worked out perfectly to use with the tonneau cover. The whole setup has been extremely simple for us to use while traveling.



by:

Happy to see that the rails and cover are now shipped in a single box although large and heavy (70lbs.) with no signs of damage. We will install this and a Yakima rack system this weekend with the help of my son-in-law and grandson for a great family project.



by:

I have these tops on both of my trucks. Very durable and the powder coating is still in excellent condition.



by:

Love the look and feel of the cover.



by:

It is great. Took about 2 hours to install. You will need 2 people to put the assembled cover in the bed. I do have the multiplex tailgate and rain water will get into the bed because of the gap in the tailgate sections.



by:

Need I say more... :)



by:

Tonneau cover was delivered to my door with no damage. Hope to install it this weekend, weather permitting.



by:

It doesn’t lock into any position very well, either have all the way open or close. At time after I unlock it then I have to open the tail gate pull it to get it to unlock.



by:

Showed up quickly, this is the 3rd purchase from etrailer.com, they have great customer service, they know their products, prices are reasonable and they ship fast. I also purchased the Curt Hitch from them.



by:

Order was processed quickly and arrive in the specified shipping time. Easy two person install and fine tuning is an easy one person job. Great quality top and rugged. Perfect top for your pickup. Bed stays water tight so storing sleeping bags or luggage is no problem on long trips.



by:

Works just as I had hoped.



by:

Easy install nice and clean.



by:

Short version, LOVE IT!!! This was a lot more money than I wanted to spend but it was well worth it. While not water tight it is close. Easy to install, easy to operate. Does not make noise even on washboard roads. The loss of space by having a canister has not impacted me. But I saved the best for last. My daughter wanted one for her truck so I ordered another one. It was damaged in shipment and the best customer service representative in the world, Kimberly O, helped me out by getting me a new replacement quickly. I highly recommend this Tonneau Cover. I also got T-Slots and use my Rhino crossbars with the cover. No problems, just like they were made for each other.



by:

I had a solid tonneau before and liked it. Only problems with it were you could not drive with the cover up and it was a bear to remove even with the help of my wife. That truck was totaled by a drunk driver. So the replacement truck had to have an easier cover and wile I was at it, why not some racks as well?
It looks great! Fits perfectly and was a synch to install.
On the down side it is not completely dry and it did freeze up once in the winter. Other than that I do like it and gave it 4 stars



by:

Thanks etrailer. Ordered the Yakima Overhaul ladder racks and the Retrax tonneau cover. It’s the perfect solution for our camping/kayaking trips. Both products are solid and top notch. Installation was a breeze on my 20 Tundra.



by:

Retrax Pro XR with Rhino Rack Cross Bar set for the XR

This has greatly simplified my bicycle transport. Before I was using separate ladder rack on back of trailer, and hitch rack on truck. Compared with my prior setup, here are the improvements:
-- removes ~75 lbs from back of my trailer
-- not dealing with separate truck and camper bike racks (esp hitch rack taking up bed room while towing)
-- don't have to unload bikes to check something on camper roof
-- bikes are easier to load (even with lifting)
-- cross bars detach in seconds and lift off for full bed access or car wash (the cross bar and bike rack assembly stores on hook in garage)
-- Don't have to remove and store bike seats (they extended well past right side of trailer when on ladder rack)
-- Bikes are more protected above tonneau cover than either on hitch rack or ladder rack.



by:

Really like this cover. Installation was fairly straightforward I was able to do the install myself but another person would have been helpful.



by:

The Retrax Pro XR cover performs and looks like new after 1 year. Took 2 of us to install and adjust properly. Very minimal water leakage around tailgate sometimes which is expected. Read reviews of water leaks but must be due to improper installation/adjustment. Very satisfied and looks great. 2024 GMC 2500HD Denali



by:

The Retrax Pro HR and Yakima Overhaul HD is a perfect combo and works well together.



by:

We really like the bed cover. Wish it was more waterproof but still really nice.



by:

I couldn’t be happier with this tonneau cover for my F450. It shipped well, arrived quickly, and was packaged securely with no damage at all. Everything was organized and protected right out of the box.

Installation was surprisingly easy — clear instructions and no headaches. I had it mounted in no time, and it fit my F450 perfectly. The alignment was spot-on and the clamps secured tightly without any modifications needed.

The cover looks great, feels durable, and gives the truck a clean, finished appearance while keeping the bed fully protected. It opens and closes smoothly and feels solid once locked down.

If you’re looking for a tonneau cover for your F450, this is a great choice. Fast shipping, easy install, and excellent quality — 5 stars all the way!



by:

Replaced my "soft" tonneau cover that was tearing, fading, and falling apart after 10 years of faithful service. Bought this tonneau cover because of the retractable operation and the aluminum construction. While it is obviously built tougher and the operation is smooth, it does have its downfalls (which I didn't think of too much at the time). One being the space that is lost in the front where all that retraction goes, I guess there is around 8 inches of height at the very front. Additionally, where it lays is slightly lower than the bed rails which takes away at least around an inch of height compared to my previous cover. This makes a big difference when getting tall containers and the like to fit. I do enjoy the elevated level of security the new tonneau cover offers, even though I had zero problems with the previous cover.



by:

Easy to order and find the correct fit. This is my third cover from this brand and my first with aluminum slats instead of polycarbonate due to a different truck size. Installation took about two hours from start to cleanup, and I needed a couple of neighbors to help lift it since the aluminum version is heavier. My previous polycarbonate covers didn’t leak and worked well, but they became slightly wavy over time. I expect the aluminum version to hold up better.

Installation note for 2026 Ram 3500 Dually: when positioning the clamps at each set of plastic allen screws had to adjust front and back clamps The front clamp near the cab bolts were a bit short due to the wider gap between bed and tonneau rail, so I removed the top back piece of the clamp to secure it properly. The lower supports did not fully reach the side walls, and the rear clamp near the tailgate required removing the lower support bolt to clear the cargo light. The middle clamps fit as intended with no adjustments. Something for the manufacture to consider as new trucks come out with different accessories.

Overall, I’ve been very happy with this brand over the years and am satisfied with this purchase.



by:

Was relatively simple to install and works as advertised. Not my first of these covers so I am a return customer and also new what to expect with installation. The PDF instructions are good, but not quite Lego or IKEA level. I haven't installed the Yakima HD Overhaul System yet, but do not expect any issues.



by:

I installed the RetraxPro XR tonneau cover myself and it wasn't bad at all. I had to do a lot of adjusting to get it perfectly straight and even. The hardest part was having my wife help me lift the cover in the truck after it was assembled. I wish they would include some kind of a reducer to be able to fit the drain hoses into the smaller holes in the bed of the truck so no drilling would have to be made. Other than that, great bed cover and can't wait to add T-slot accessories.
