Features to know about
Secure Everyday Gear: Locking Retractable Cover
If you keep tools, sports gear, or groceries in your truck bed, this cover keeps them safe from both weather and theft. The RetraxONE MX locks at any point along its rails with a pop-up handle that stays flush and hidden under a lid. When closed and used with a locked tailgate, it gives solid protection that can’t be cut or pried open like soft covers. The design also lets you latch it partway to shield smaller items while leaving space for longer cargo at the back.
Smooth Access in Seconds: Sealed Ball-Bearing Rollers
Getting full use of your bed doesn’t mean wrestling with snaps or straps. The RetraxONE MX slides open and closed on sealed ball-bearing rollers that never need lubrication and won’t bind or freeze. You can move it with one hand from either side of the bed, and the retractable design rolls neatly into a compact canister at the bulkhead. The spiral track system keeps the panels from rubbing against each other, so the cover stays smooth and trouble-free over years of use.
Withstands Weather and Impact: Polycarbonate Construction
Built from tough polycarbonate (Lexan) reinforced with 5/8" thick aluminum I-beams every 4-3/4", this cover is made to take hits without denting or cracking. It’s rated to hold 200 lbs of evenly distributed weight and stays stable from -50 to 200° F without warping or swelling. The matte black finish is scratch-resistant, UV-protected, and cooler to the touch than metal on hot days. That means it keeps its look and performance through snow, sun, and everything in between.
Keeps Cargo Clean and Dry: Weather Seals and Drain Tubes
Rain, snow, and road dust stay out thanks to tight weather stripping and foam seals along the rails, plus a cover lip that overlaps the tailgate. Any water that sneaks into the canister is channeled out through two included drain tubes. The angled bottom of the canister also leaves more room for gear underneath, so you don’t lose usable bed space while keeping moisture away from what’s stored inside.
Low-Profile Fit: Streamlined Style and Easy Installation
Sitting just 1" above the bed rails, the RetraxONE MX gives a clean, flush look that blends with the truck’s lines. The rails clamp on with no drilling required, so setup is straightforward and doesn’t damage your bed. Once installed, you get a smooth, low-profile tonneau that reduces drag and helps protect your cargo without adding bulk.

Everything was on time and good quality. Easy to install, but you need to open the lock before installing the rail. If the lock is in the lock or down position the rail won’t go on. Other than that it was easy and it looks great on the truck!

It is a nice cover over all, install was quick and easy. However, the cover is a bit flimsy. While sitting there you can see slight high and low spots from one slat yi the next. And while driving the cover moves quite a bit in the wind. Had I known this i would have just paid the extra for the aluminum version. Like I said, it's a nice cover over all it just needs to be a little more rigid.

I purchased and self-installed this cover on my 2024 Chevy Colorado ZR2. Tracking of the shipment was spot on. Excellent communication by Kelly (etrailer customer support). Installation was simple and straightforward. The quality of the cover is excellent. Made in the USA. I highly recommend this cover.

This is my second Retrax poly cover. i had my first one for about 10 years and it worked well the entire time. I finally purchased a new truck and had to pick another cover and picked this one again for the quality and durability.

I like how the top rolls up and out of the way when not needed. I should have ordered the Pro with the aluminum top. The composite top moves quite a bit when closed and driving down the road.

One year update: My RetraxONE MX still looks and performs good. For my application (fifth wheel protection) it was a good choice.

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.

It is extremely hard to open and close even with grease on the rails and proper alignment.

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.

I spoke with Jesse who was very helpful in helping me pick out this product for my 2006 Toyota Tacoma. He was also very helpful when he informed me that I needed a tailgate lock. The product arrived in a timely manner and was as advertised. My daughters and I set up the RetraxONE MX Hard Tonneau Cover pretty quickly. The installation was simple and straight-forward. Would purchase again from etrailer.

I was pleasantly surprised by the quality and durability. I like the ability to cover, lock and latch in partially closed position to help support large items. I'm sure I'm getting a little bit better gas mileage because of the drag reduction off the bed. The only drawback: the space that the canister takes up reduces your bed size. It hasn't impacted me yet as I have the larger bed size. If you have a bed extender, that will help. I definitely like the retractable better that the folding ones.

The unit shipped to my location with over a months delay. This was too late for our last camping trip of2 2021, which I was counting on using it. I installed this year instead. Some of the tapped holes need to be re-tapped. Also, drain plugs were a little tricky in that the hose interfered with that latching mechanism, so they did not latch correctly at first. The roll-up into the box does not seem as smooth as the videos seem to show. Roll down to close is smooth.

A little challenging at first with the directions but with my neighbor helping we pulled through. 3-4 hours of slow methodical reading and working. Very nice product looks great and works as advertised.

We love this cover! I will most likely be ordering another one because unfortunately I got trapped in a terrible hail storm and the cover was damaged. No way any covered would have survived.
Thank you

- Troubleshooting RetraxONE MX Cover Leaking at Tailgate on a 2016 Ford F-150 with 5-1/2 BedI reached out to my contact at Retrax who said that the number you gave me means that you have the RetraxONE MX Hard Tonneau Cover # RT60373 on your 2016 Ford F-150 with the 5-1/2' bed. If your cover is leaking at the tailgate and you have already tried replacing some of the seals then my contact at Retrax said it sounds like the rubber seal that is connected to the cover itself is in bad shape. Unfortunately that is not available as a separate part so the only way to change that out is...

- Will A RetraxPro MX Tonneau Cover From A 2021 Ford F-150 Fit A 2015 Ford F-150 The RetraxPro MX that fits your 2021 Ford F-150 is unfortunately not a compatible match for a 2015. Your friend will need one of the other models that are compatible with a 2015, like the RetraxONE MX Hard Tonneau Cover # RT60373 instead.

Not only does the RetraxONE MX sit just 1" above the truck bed for a flush look, it also includes a locking handle for ultimate security. The handle allows you to lock the cover at any point along the bed rails. When the cover is closed/locked along with the locked tailgate, this provides amazing theft-deterrence. It comes...

It is actually a combination vinyl and aluminum cover but it still rolls up. This design is also going to prevent the cover from flapping or bubbling. To lock it you would just have to lock the tailgate because the cover cannot be rolled up without lowering the tailgate to access to the latches. For a similar cover that doesn't have the...

So let's start with the tonneau, and since you want to ensure protection for your truck bed, the best option is definitely a locking cover, and for that I highly recommend the RetraxONE MX Hard Tonneau Cover # RT60373.
