RetraxONE MX Retractable Tonneau Cover video review
Video by Stage 3 Motorsports on YouTube. Independent creator content, shown as a reference. It is not part of our scoring.
The RetraxONE MX is Retrax’s lower-priced manual retractable: one-piece polycarbonate slats on aluminum I-beams that slide into a canister at the cab and lock with a key. Amazon listed the 2021–2026 Ford F-150 5’7” version (part 60378) at about $1,550 on November 12, 2026, roughly $370 less than the aluminum RetraxPRO MX. We haven’t tested it ourselves; this review is built from Retrax’s specs, retailer data and owner reports. Check your bed in the bed size finder, and see the full ranking in our best tonneau covers of 2026.
Who it’s for (and who should skip it)
It’s for buyers who want the main reason to own a retractable, a key lock that holds wherever you stop the cover, without paying aluminum-slat prices. If you rarely load anything on top of the cover, the lower load rating won’t matter.
Skip it if you stand on the cover, stack gear on it or want the longest warranty: the PRO MX is rated for 500 lb and has full lifetime coverage. If a foot of bed matters more than a key lock, a folder that stands upright, such as the BAKFlip MX4, opens the whole bed for less.
Security and locking
The ONE MX comes with a key that locks it at any position along the rails, according to Retrax, so it stays locked even with the tailgate down. That puts it at level 3 on our security scale. Polycarbonate is tough, but it isn’t aluminum: etrailer lists a 200 lb evenly distributed rating, and polycarbonate scuffs more easily than powder-coated metal. The listing says the powder-coated finish adds UV and scratch resistance.
Bed access and everyday use
It shares the PRO MX’s canister: etrailer lists 13-1/2 in deep by 12 in tall. On a 2021+ F-150 short box (67.1 in) that leaves about 53.6 in open, about 80% of the bed, with the cover fully retracted. Longer beds lose a smaller share. The bed access calculator draws it to scale for your truck.
Retrax says the one-piece slats have no hinges to collect grit. Opening is from the driver-side rear latch, per etrailer, and the listing weight is 70 lb, lighter than the 90 lb PRO MX.
Weather sealing and drain tubes
Like every retractable, it relies on rail seals plus drain tubes to carry water out of the canister. etrailer notes two drain tubes routed through the existing bed drain holes. We found no independent water test of the ONE MX. Car and Driver’s test of the GatorTrax retractable found leaks at the cab-side corners and from the canister until a drain was added, which is a fair picture of the category’s weak spots. See are tonneau covers waterproof?
Install and fitment
The listing describes an install you can do yourself or with a friend. Retrax advertises no drilling for the cover itself, but etrailer’s installer had to drill through a spray-in bed liner for the drains.
We checked these listings: F-150 2021–2026 5’7”, Ram 1500 2019–2026 5’7” (not the Multi-Function tailgate), Silverado/Sierra 1500 2019–2025 5’10” (MultiPro/Flex OK, not CarbonPro; a separate CarbonPro version exists), Tacoma 2016–2023 Double Cab 5’1”, and Tundra 2022–2025 5’7” with the deck rail system. Prices ran about $1,550–$1,650. Use the listing’s fitment tool to confirm.
What you’ll need beyond the box
- A bed mat, such as the Rough Country rubber mat for the F-150 5’7” bed, to stop cargo sliding into the canister.
- Racks: clamp-on systems that list retractable covers, such as the Thule Xsporter Pro Shift, are the usual route. Check Retrax’s compatibility list first; retailer Q&A says the Yakima OverHaul HD doesn’t fit.
- Cargo control, like a ratcheting cargo bar.
See the accessories page for more.
Reliability and warranty
Retrax gives the ONE MX a 1-year full warranty followed by a limited lifetime warranty (maker claim). The F-150 listing showed 26 ratings at 4.4, and the Ram listing 168 ratings at 4.4.
Bottom line
The RetraxONE MX gets you a keyed, lock-anywhere retractable for about $1,550 on the F-150. You give up load rating (200 lb vs 500 lb), some scratch resistance and warranty length compared with the PRO MX, and like any retractable you lose about a foot of bed to the canister. For owners who never load the top of the cover, it’s the better-value Retrax. Compare all the options in our best retractable tonneau covers, or check the price.
Accessories that pair with the RetraxONE MX
Cover care, bed racks, mats and cargo gear sold on Amazon. Most bed and floor products are vehicle-specific: the fitment shown is the listing we checked, so search the same product for your truck if yours differs.
- Bed rackThule Xsporter Pro Shift truck rack (500010)Compatible, third-party
Sliding 18 in towers that move along the bed for different loads, rated to 600 lb per the listing. A rack that rides on its own rails is the usual way to combine bars with a retractable cover. Requires Thule TracRac base rails (sold separately). The listing says it's compatible with retractable tonneau covers 'see fit guide', so confirm your exact cover in Thule's fit guide.
- Bed rackThule TracRac SR base rail (217870)Compatible, third-party
The drill-free base rails the Xsporter Pro Shift and TracRac SR racks mount to. Needed for the Xsporter Pro Shift; check Thule's fit guide for your truck and cover before ordering.
- Bed rackYakima OverHaul HD adjustable truck bed rack (8001151)Works with any cover
Height-adjustable towers with T-slots and SKS locks, rated 500 lb on-road and 300 lb off-road per the listing, for rooftop tents, ladders and boats. The Amazon listing doesn't state tonneau-cover compatibility. Check Yakima's fit guide for your truck and cover before buying.
- Cargo managementKeeper ratcheting cargo bar, 40–70 in (05059)Works with any cover
Pins groceries and gear against the bulkhead or tailgate so nothing slides around under a closed cover. It sits below rail height, so the cover closes over it. 40–70 in span; measure between your bed walls at the height you'll use it.
- Cargo managementRhino USA ratchet straps, 1 in × 15 ft (4-pack)Works with any cover
Tie-downs for loads strapped to a bed rack, or tall cargo you haul with a roll-up or folding cover open.
- Cargo managementMigaven heavy-duty truck bed cargo net, 4 × 6 ftWorks with any cover
The fallback when a load sticks up past the rails and the cover has to stay open: a stretch net over the bed keeps loose items in.
- Cargo managementRough Country slide-out truck bed cargo tray (10209)Works with any cover
Brings small items to the tailgate so you don't have to crawl under a cover to reach the front of the bed. Rough Country says the 4 in tray fits under any bed cover. Listing fitment: Trucks with a 5'7" or longer bed (tray is 62.3 × 23.6 × 4 in). Per the listing, fits beds 5'7" or longer; 5 ft midsize beds are too short.
- Cargo managementDECKED drawer system (XR7)Works with any cover
Two bed-length lockable drawers under a flat deck rated for 2,000 lb of cargo per the listing. Under a locking cover, it turns the bed into secure tool storage. Listing fitment: 2019–current Ram 1500 (DT) 6'4" bed, not RamBox. A drawer system raises the bed floor, which cuts the height left under a cover. DECKED sells a separate model for each truck and bed length.
- Bed matHusky Liners custom-fit rubberized bed mat (16008)Works with any cover
A rubberized mat with air-dry nibs underneath, so water that gets past a soft cover's seals can drain instead of sitting on the paint. Listing fitment: 2015–2026 Ford F-150 and 2022–2026 F-150 Lightning, 5'7" bed. Per the listing, it will not fit over a drop-in bed liner.
- Bed matRough Country heavy-duty rubber bed mat (RCM671)Works with any cover
A cheaper rubber mat that protects the floor and keeps cargo from sliding into the tailgate. Listing fitment: 2015–2027 Ford F-150, Lightning and Raptor, 5'7" (67 in) bed.
