Features to know about

Secure Storage in Any Weather: 1" Thick Aluminum Construction

When you’re carrying expensive tools or gear, you want a cover that locks up tight and doesn’t cave under harsh conditions. The RetraxPRO XR uses 1" thick aluminum slats that are impact and weather resistant, supporting up to 500 lbs of evenly distributed weight. The matte black finish is scratch resistant and won’t fade in the sun, keeping it looking sharp year after year. Weather stripping and foam seals surround the edges to keep out water, dust, and snow, while the overlapping top panel helps prevent leaks at the tailgate.

Full Bed Access Without Hassle: Smooth, Retractable Design

You don’t have to wrestle with snaps or folding panels when you need to haul something tall. The sealed ball-bearing rollers glide the cover open and closed smoothly without lubrication or binding. You can stop and lock it anywhere along the rails, so you can secure smaller gear up front while leaving space for larger items in the back. When fully open, the cover rolls into a compact canister with an angled bottom that saves bed space and leaves room for long cargo underneath.

Add More Carrying Options: Built-In T-Slots for Racks

If you haul bikes, kayaks, or ladders, the integrated T-slot track system is a big plus. You can mount T-slot compatible racks from Yakima, Thule, Rhino Rack, and others directly to the side rails. That gives you room to carry gear above the bed without interfering with the cover’s retracting motion. The setup is perfect for overland builds or anyone who needs extra carrying capacity without sacrificing bed security.

Quick Setup and Clean Fit: Low-Profile, No-Drill Mounting

Getting this cover installed is simple and doesn’t require drilling into your truck. The side rails clamp directly onto the bed rails and sit just 1" above them for a sleek, low-profile appearance. The flush-mounted locking handle blends in neatly and lets you open or close the cover independently of the tailgate. Two drain tubes at the bottom of the canister channel water out through factory holes to keep everything dry and clean inside.

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



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:

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:

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:

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:

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:

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.

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.

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 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.

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!

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.

Great, I love that it locks all the way up and down the track. Works great



by:

Nice product. Had shipping damage etrailer made it right.



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
