Retrax Tonneau Cover - RT80485
Highlights
- Custom Fit for Your Vehicle: Secures to your truck bed with model-specific clamps and hardware
- Keeps Gear Safe: 1" thick aluminum slats lock anywhere along the rails for secure coverage.
- Full Bed Access Fast: Retracts smoothly into a compact canister without removing the cover.
- Stays Dry: Weather stripping, foam seals, and drain tubes channel out moisture and dust.
- Built to Last: Matte black aluminum resists dents, scratches, and sun fade; holds 500 lbs.
- Clean Low Profile Look: Rails sit just 1" above the bed for a sleek, streamlined finish.
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.

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.

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!

Really can not rate any better. It has not been installed yet. Once box with the bed rails arrived busted open. The rails appear okay but will have to wait until the install next week. The large heavy box was partially crushed on the bottom where it was apparently transported. Have not opened box yet.

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.

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.

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.

Install looks great Jesse! We couldn’t agree more about the instructions. Honestly, unclear instructions are exactly why we started making our own install videos many moons ago, because seeing it done can make all the difference. It’s good to hear the cover feels solid and slides smoothly once installed. Your notes on water sealing and debris are fair, especially with RamBox-equipped beds and tailgate fitment. We appreciate you sharing your experience, and we hope it continues to serve you well over time.

This is a very sturdy tonneau cover and looks great on our 2026 Ford F-450. The materials and build quality are top-notch. The installation is straightforward, and I recommend you watch the video(s) prior to performing the installation. The unit is heavy, and you will need a strong helper. This is our first hard tonneau cover, and we are very pleased with our purchase.

The shipment was supposed to be delivered yesterday, so I stayed home from work to receive it. I live on a busy street in St. Louis city, or a corner lot. The instructions were to deliver it around back to the garage door. It finally arrived after 9pm on the front steps, which are within 8 feet of the sidewalk. Good thing it's so heavy and it didn't "walk off".

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.

So on the plus side, love how it opens all the way up. When were loading the bed for travel, I need it fully open. Downside is the amount of room the canister takes up and the water as previously mentioned. Still quite easy to use!

@Laura970 I am glad it is working well for you on some aspects. I am wondering if the weather stripping or seal is bad. Have you noticed certain areas where the water leaks in more than others or is it pretty difficult to tell when it rains?

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!

view full answer... - Locking Tonneau Cover that Maximizes Bed Space and Visibility for 2021 Ford F350 Short BedThe best option to meet all the parameters you mentioned would be to use a roll up cover like # LE96VR from Leer. When it's rolled up, it won't completely block your view out the rear window and won't take up much if any room in the truck bed. If your tailgate locks, the latches that allow the cover to be rolled up will be inaccessible as long as the tailgate is closed and locked. This will be your best bet, as a folding cover will block your view out the rear window, and a roll up cover...

It might be fine but it's not been tested for that so it's hard to say if there would be any issue. A roll up tonneau like the part # BAK64FR that fits your 2021 GMC Sierra 3500 might you be best option as when it's rolled up there would be nothing below the tops of the bed rails to get in the way of tying down your motorcycle. This is also a hard cover too for added security.

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.
