Features to know about

Smooth Operation Every Time: Sealed Ball-Bearing Rollers

Some retractable covers can bind, drag, or need constant lubrication. This one glides effortlessly thanks to sealed ball-bearing rollers that move the cover evenly along the rails. There are no springs, straps, or hinges to wear out or jam in cold weather, so it always rolls smoothly. The pop-up handle lets you open and close it with one hand, and you can stop and lock it anywhere along the rails to cover part of the bed while hauling longer gear.

Strong Enough for Work or Weather: 1"-Thick Aluminum Slats

When you need a tonneau that can take real use, the 1"-thick aluminum construction delivers. It’s impact and weather resistant and rated to support up to 500 lbs of evenly distributed weight. The heavy-duty matte black finish resists scratches and fading, so it stays looking sharp even after years of sun, snow, and dirt.

Weather Protection that Lasts: Seals and Drain Tubes

Keeping cargo clean and dry is easy with the built-in weather stripping and foam seals on all sides. The cover overlaps the top of the tailgate to block out water and dust, while drain tubes built into the canister route any collected water safely out of the bed. The spiral track inside the canister keeps the cover from rubbing against itself, so it won’t wear through over time.

Low-Profile Look with More Bed Space

Unlike bulky folding lids, the RetraxPRO MX sits just 1" above the bed for a clean, streamlined look. The angled canister bottom leaves more room underneath for long or small items, and when the cover is closed it blends flush with the rails for a solid, factory-style finish.

Simple Setup: No-Drill, Clamp-On Installation

Mounting the cover doesn’t require cutting or drilling. The canister comes pre-assembled, and the side rails clamp directly to the bed rails. Once the rails are squared, just tighten the clamps, attach the drain tubes, and it’s ready to use. The result is a secure, retractable aluminum cover that installs quickly and operates easily every day.

The RetraxPRO MX Hard Tonneau Cover was very easy to assemble and install. Item was packaged very well for shipping. I would recommend this tonneau cover.



by:

Very well built and easy to use, great product.



by:

Vert good quality. No failures despite repeated use.



by:

This cover looks amazing and rolls so smooth. No heavy trifold flipping. I have the 8’ bed and it works great.



by:

On my previous truck, we had installed a soft snap-on tonneau cover. While it looked great, its performance over time decreased significantly, particularly in cold weather! So this time around, I decided to splurge and purchase a high-quality roll-top hard cover. I am SO HAPPY that I did! As importantly as its ease of installation and use, it is lockable so I will no longer have sleepless nights while traveling, worrying about the items in the truck bed. eTrailer was a great help in expediting the delivery of this item, as my HOA requires pickup trucks to have their beds covered... Thank You!



by:

I like the old latch system better.
The
wire loom for drains is not going to last long.



by:

Great quality very happy with this. Would recommend to anyone looking for a nice retractable cover.



by:

Item came on time and was very easy to install, but you need somebody to help you lift and put in the back of the truck as instructed. Its not that heavy, but just too awkward for one person to lift and place.



by:

The tonneau works well. I wanted something that would be pretty secure (aluminum and locking) and easy to open/close. It is all those things! One handed open/close. Few pieces that are below the cover level so it doesn't interfere too much with what you have in the bed. Install was ok - definitely two people are easier than one.
Two downsides. The roll up area does take bed space - more than I'd like. Also, it is not watertight. Not terrible in the rain, but a good downpour or car wash gets water in the bed.



by:

Quality product. Bought to protect and hide fifth wheel hitch. Does a great job!



by:

Nice product. More difficult to get the rails attached than it should have been. Very glad I had 2 strong guys helping me.

Love the results.



by:

Should put actual installation instructions with the product inadition with the on line.Something was catching when attempting to operate. Semes to work ok after it broke free.



by:

Received my order in a timely manner. It was an easy install. I’m 65 years old and was able to install by myself.



by:

The instructions were definitely lacking—ended up finding a decent YouTube video. The box itself wouldn’t fit between the rails on the inner sides of the bed (see pics), so I had to use prybars to seat it past the rails.

Functionality: seems very solid once installed and rollers help it slide easily either direction. I’m not convinced it’ll hold much water out, but that’s partly due to the ram box hinges next to the tonneau rails, then not a lot of pressure between the tonneau and the top edge of the tailgate. I also had a $500 tonneau in the past with weather stripping along the front box to scrape debris from the top side of the tonneau as it retracts into the box at the front of the bed. This doesn’t have that, so it seems debris will accumulate inside the box and I’m not sure how easily it will be to clean inside the box.

Time will tell if this is worth the price tag, but it does feel very sturdy once installed.

Down to 3.5 stars. Have had a couple of issues with the clamping mechanism at the side rails. The rail actually has a hole almost all the way through it now. I put a rubber stopper there to help keep it from getting worse.

Thank you for your review. You can reduce the wear that the pin is causing by adjusting it down slightly with a hex wrench. If you are still having issues I would contact Retrax about their warranty.

Assy was easy looks great

Very nice product with excellent installation instructions and videos.



by:

Love the looks and ease of install and function of cover. After ordering and THEN finding the cover was NOT in stock, I contacted etrailer for shipping updates only to be advised it was backordered several weeks. Contacted Retrax directly and got solid information on delivery(which was actually before scheduled date). Unfortunately it arrived looking like it was thrown out of a 2nd floor window and the spirals were destroyed. Retrax customer service is top notch and had a replacement canister shipped quickly.

Missing mounting hardware. Sent a message 6 days ago and still no answer about missing hardware.

I'm sorry that happened William, I'll get that taken care of for you!

This was a really easy installation. 2026 GMC 3500 DRW. I did it the install myself pretty quickly (except for lifting the combined rail/cover into the truck). One person on each side to guide and lift while my daughter lifted the weight in the middle of the bed worked well. The few connection screws required fit easily. Seals at the front of the truck and on the tailgate are smooth and complete. I didn't make both sides parallel when first installed. I loosened the middle and tailgate ends of the rails, adjusted the spacing distances, and it's perfectly in align now. One person can very easily expand and contract the top. The two drain hoses won't fit the holes in the truck bed. I'll pickup something from Home Depot or Lowes to append a reducing method. I really like this bed cover!

That is great to hear! I am glad you were able to get this installed easily with a little bit of help. I am sure you will like this cover over time. Are you using that new truck to tow anything?

@Michael That is awesome! You'll have to let me know how those work as well.

I was hesitant to try a canister type roll up bed cover after only having hard covers or a soft roll up above bed cover before. I'm glad I did...

It still gets 5 stars because even though the box for the rails was damaged, no parts were missing and there were no dents or scratches on any of the pieces.

The install was easy, did it by myself in a couple of hours not rushing to get it done but working at a leisurely pace. The only time I needed help was to position it in place after the side rails were attached. The part that took the longest was measuring and adjusting the width between rails from the front to the back to get them within spec so the cover moves smoothly and easily with no binding. The instructions were easy to follow and it is simple to put together and install. Just take your time measuring between the rails and it will glide effortlessly.

I like the size of the canister, it doesn't take up much space at the front of the bed, even though it has 8ft to roll up. It seems as if it will be pretty water repellent with the rubber seals and gaskets. It rolls up easily and doesn't retract fast and slam into the canister. It also rolls out easily all the way to the tailgate. Unlike previous covers I have had, this one doesn't require the tailgate to be closed to work properly. The cover can be extended all the way to the tailgate and you can open and close the cover or tailgate independently of one another. I also chose this particular cover because it had the anywhere lock feature rather than only a few set locking points. The matte aluminum is a nice clean look, and it seems like it will be less prone to sagging in the middle as time goes by. This particular model sits just a little above the bed (the bed cover rails sit on top of the truck bed) but the canister isn't any higher than the rails or the cover itself when its open or closed. It looks seamless and clean.

It's only been a few days since install but as of now, I couldn't be happier having chosen this bed cover. And as always, etrailer makes the ordering process easy and worry free with their vehicle specific fit, fast shipping and fair prices.

After about a year owning this cover, I still would buy it again. If you set it up right in the first place, it will work flawlessly. The locking mechanism still works great. The rolling part still works great. Aside from a solid cover, this is the most secure cover I have ever had. It does get some drips of water inside after washing the truck but its not enough to worry about, even if you had a bed full of stuff.
