# Best Retractable Tonneau Covers 2026: 3 Picks Compared > The best retractable tonneau covers of 2026: RetraxPRO MX, RetraxONE MX and Roll-N-Lock M-Series compared on canister size, load rating, locks and price. - Source: https://truckcoverguide.com/posts/best-retractable-tonneau-covers/ - Markdown version: https://truckcoverguide.com/posts/best-retractable-tonneau-covers.md - Last updated: 2026-11-12 --- - [Home](https://truckcoverguide.com/) - [Guides](https://truckcoverguide.com/guides/) - The Best Retractable Tonneau Covers of 2026: RetraxPRO MX, RetraxONE MX and Roll-N-Lock Compared Retractable # The Best Retractable Tonneau Covers of 2026: RetraxPRO MX, RetraxONE MX and Roll-N-Lock Compared Updated November 12, 2026 By [Truck Cover Guide Editorial Team](https://truckcoverguide.com/about/) [How we research](https://truckcoverguide.com/how-we-research/) Prices are approximate and change often, so check the current price before you buy. ## Key takeaways - **RetraxPRO MX** is our pick: powder-coated aluminum slats rated for 500 lb, a key lock that holds at any position and a lifetime warranty, from about $1,917 on the F-150 5.5 ft. - The **RetraxONE MX** keeps the lock-anywhere convenience for about $370 less, but it's rated for 200 lb rather than 500 lb. - Canister size is the big difference: Roll-N-Lock quotes 7-1/4 in deep for the M-Series, while etrailer lists the Retrax canister at 13-1/2 in deep by 12 in tall. - No retractable is watertight. Car and Driver's tested retractable leaked at the cab corners and from its canister, and drain tubes are essential. ## Our top picks - 1![RetraxPRO MX Retractable Tonneau Cover](https://truckcoverguide.com/_astro/retraxpro-mx.CQ7vuEa8_Z1anuev.webp)Best retractable overall: aluminum slats, 500 lb rating, key lock at any position, about $1,917 for the F-150 5.5 ft[RetraxPRO MX Retractable Tonneau Cover](https://truckcoverguide.com/tonneau-covers/retraxpro-mx/)Retractable · Aluminum slats · 80% bed access · Keyed lock7.4**$$$$**Top-endPrice tier: Top-end[Check price on Amazon](https://www.amazon.com/dp/B08L46PC1S?tag=truckcoverguide.com-20) - 2![RetraxONE MX Retractable Tonneau Cover](https://truckcoverguide.com/_astro/retraxone-mx.C3rZ0CtS_ZSFkSM.webp)Best value retractable: the same lock-anywhere design in polycarbonate, about $1,550 for the F-150 5.5 ft[RetraxONE MX Retractable Tonneau Cover](https://truckcoverguide.com/tonneau-covers/retraxone-mx/)Retractable · Polycarbonate slats · 80% bed access · Keyed lock7.3**$$$**$PremiumPrice tier: Premium[Check price](https://www.amazon.com/dp/B08L45SKMN?tag=truckcoverguide.com-20) - 3![Roll-N-Lock M-Series Retractable Tonneau Cover](https://truckcoverguide.com/_astro/roll-n-lock-m-series.D0QHCItG_5cft.webp)Most bed space: 7-1/4 in deep canister, T-slot rails on the XT, about $1,800–$2,000[Roll-N-Lock M-Series Retractable Tonneau Cover](https://truckcoverguide.com/tonneau-covers/roll-n-lock-m-series/)Retractable · Vinyl over aluminum · 89% bed access · Keyed lock7.3**$$$$**Top-endPrice tier: Top-end[Check price](https://www.amazon.com/dp/B09N9TRSM5?tag=truckcoverguide.com-20) ### On this page 9 sections - [The shortlist](#the-shortlist) - [1.

Slats slide into a canister at the cab, there’s nothing to fold, roll or strap, and the good ones lock with a key at any position along the rails. You pay for that in money and in bed space. This guide compares the three retractables we track: the [RetraxPRO MX](https://truckcoverguide.com/tonneau-covers/retraxpro-mx/), the [RetraxONE MX](https://truckcoverguide.com/tonneau-covers/retraxone-mx/) and the [Roll-N-Lock M-Series](https://truckcoverguide.com/tonneau-covers/roll-n-lock-m-series/). We haven’t tested these covers ourselves. Specs below are maker claims from the Amazon listings and from the retailer etrailer, which reproduces maker spec sheets. Where a hands-on test result appears, we name the outlet that ran it. Prices are what Amazon showed on November 12, 2026, for the trucks listed; covers are made per truck, so check the listing for yours. ## The shortlist | Cover | Slats | Canister (cab end) | Load rating | Lock | Warranty | F-150 5.5 ft price | | --- | --- | --- | --- | --- | --- | --- | | [RetraxPRO MX](https://truckcoverguide.com/tonneau-covers/retraxpro-mx/) | Aluminum | ~13-1/2 in deep (etrailer) | 500 lb | Key, any position | Lifetime (limited) | ~$1,917 | | [RetraxONE MX](https://truckcoverguide.com/tonneau-covers/retraxone-mx/) | Polycarbonate | ~13-1/2 in deep (etrailer) | 200 lb | Key, any position | 1 yr full + limited lifetime | ~$1,550 | | [Roll-N-Lock M-Series](https://truckcoverguide.com/tonneau-covers/roll-n-lock-m-series/) | Vinyl over aluminum | 7-1/4 in deep (maker) | Not published | Key | 3 yr | ~$2,000 (XT) | All three sit low on the rails, and all three are level 3 on our [security scale](https://truckcoverguide.com/posts/most-secure-tonneau-covers/): a hard cover with its own key, so the bed stays locked even when the tailgate is down. ## 1. RetraxPRO MX: Best retractable overall The [RetraxPRO MX](https://truckcoverguide.com/tonneau-covers/retraxpro-mx/) is the one we’d buy. Its powder-coated aluminum slats are rated for 500 lb evenly distributed, the highest of the three, and the key lock holds the cover at any point along the rails, so you can leave it a third open for a ladder and still have it locked. Retrax backs it with what it calls a Legendary Lifetime Guarantee, a limited lifetime warranty. Prices vary a lot by truck. Amazon showed about $1,917 for the 2021–2026 F-150 5.5 ft, the 2019–2026 Silverado/Sierra 5’10” and the 2023–2025 Colorado/Canyon, but about $2,300 for the Ram 1500 5’7”, the 2016–2023 Tacoma and the 2022–2025 Tundra. Retrax also sells T-slot (RTT-) and XR rail versions for bed racks. The trade-offs are the canister and the water. etrailer lists the canister at 13-1/2 in deep by 12 in tall (in another place it gives 11-5/8 in tall by 13-3/4 in), so plan on losing about the first foot of bed. And one owner review on etrailer says it isn’t watertight in heavy rain or a car wash, which matches what testers find with retractables generally. [Check the RetraxPRO MX price](https://www.amazon.com/dp/B08L46PC1S?tag=truckcoverguide.com-20). ## 2. RetraxONE MX: Best value retractable The [RetraxONE MX](https://truckcoverguide.com/tonneau-covers/retraxone-mx/) gives you the main reason to buy a retractable, the lock-anywhere key, for less. Amazon showed about $1,550 for the F-150 5.5 ft, roughly $370 under the PRO MX, and about $1,550–$1,600 for the Ram, Silverado, Tacoma and Tundra versions we checked. The difference is the slats. They’re one-piece polycarbonate on aluminum I-beams rather than aluminum, rated for 200 lb rather than 500 lb, and polycarbonate scuffs more easily than powder-coated aluminum. etrailer lists a -50°F to 200°F temperature range and the same 13-1/2 in canister. The warranty is a 1-year full warranty, then limited lifetime. If you never put anything on top of the closed cover, the ONE MX is the smarter Retrax. If you might set a cooler, a box or a person’s weight on it, pay for the PRO. [Check the RetraxONE MX price](https://www.amazon.com/dp/B08L45SKMN?tag=truckcoverguide.com-20). ## 3. Roll-N-Lock M-Series: Most bed space The [Roll-N-Lock M-Series](https://truckcoverguide.com/tonneau-covers/roll-n-lock-m-series/) is the pick if every inch of bed counts. Roll-N-Lock says its canister is the most compact of any retractable, 7-1/4 in deep, about half the Retrax figure. The cover itself is vinyl over an aluminum undercarriage with a torsion spring in a 3 in aluminum casing, and it locks with a key. The F-150 5.5 ft listing we found is the M-Series XT (about $2,000), which adds MaxTrak rails that take most T-slot accessories from Yakima, Thule and Rhino-Rack, per the maker. That makes it the easiest retractable to pair with a [bed rack](https://truckcoverguide.com/posts/tonneau-cover-with-bed-rack/). The Ram 5’7” XT was about $1,850 and the 2022–2024 Tundra M-Series about $1,800. There are real caveats. The listings publish no load rating, the warranty is 3 years, and the Amazon track record is thin (3 ratings on the F-150 XT listing). [Check the Roll-N-Lock M-Series price](https://www.amazon.com/dp/B09N9TRSM5?tag=truckcoverguide.com-20), or read our [RetraxPRO MX vs Roll-N-Lock M-Series](https://truckcoverguide.com/posts/retraxpro-mx-vs-roll-n-lock-m-series/) head-to-head. ## How much bed does the canister cost? Every retractable stores its slats in a canister bolted to the bed floor behind the cab. That space is gone for tall cargo and for floor cargo. Here’s what that means on the 2021+ F-150’s 67.1 in short box, using the figures above: | Canister depth | Bed length left | Share of the bed | | --- | --- | --- | | 7-1/4 in (Roll-N-Lock, maker claim) | ~59.9 in | ~89% | | 13-1/2 in (Retrax, per etrailer) | ~53.6 in | ~80% | On a longer bed the canister costs a smaller share, so retractables make more sense on a 6.5 ft or 8 ft bed than on a 5 ft midsize bed. Here’s how every cover type compares on the same 5.5 ft bed: What each cover type leaves usable on a 5.5 ft bed Side view, cab on the left, 67.1 in bed floor (the 2021+ F-150 5.5 ft box). Open bed Covered by the opened cover (low cargo still fits under) Floor taken by a canister Soft roll-up Includes our estimate 88% 4 ft 11 in open-top Hard roll-up Includes our estimate 79% 4 ft 5 in open-top Soft tri-fold, folded From maker/retailer figures 67% 3 ft 9 in open-top Hard tri-fold, folded From maker/retailer figures 67% 3 ft 9 in open-top Hard fold, stood up Includes our estimate 91% 5 ft 1 in open-top Retractable From maker/retailer figures 80% 4 ft 6 in open-top Hinged one-piece From maker/retailer figures Low cargo only close to drive Run your own bed length in the [bed access calculator](https://truckcoverguide.com/tools/bed-access-calculator/). Run your own truck in the [bed access calculator](https://truckcoverguide.com/tools/bed-access-calculator/#truck=ford-f150-2021&bed=supercrew-5.5). Its retractable row uses the larger Retrax canister, so a Roll-N-Lock leaves about 6 in more than it shows. ## Water, drains and install Retractables are the hardest type to keep dry. The slats run in side rails, and water that gets past the rail seals ends up in the canister, which is why every one has drain tubes. Car and Driver’s hands-on test of a GatorTrax retractable on a Colorado found water at the cab-side corners and edges, and the cover “leaks extensively from the canister” when rolled up until a drain tube is fitted, which on that cover meant drilling into the bed. The tester also could only lock it fully closed or fully open, despite the any-position claim. That’s a different brand, but it shows what to check. For the Retrax and Roll-N-Lock covers here: - **Route the drain tubes properly.** They run from the canister through the bed’s existing drain holes. If you have a spray-in liner over the holes, you’ll need to open them; etrailer’s installer had to drill through a spray-in liner on a RetraxONE MX. - **Keep the rails clean.** Grit in the rails is what makes retractables stiff, and Retrax says its aluminum slats are made to retract without trapping debris. - **Expect some water in heavy rain.** Our [are tonneau covers waterproof?](https://truckcoverguide.com/posts/are-tonneau-covers-waterproof/) guide covers what to expect from each type. ## Retractable vs the alternatives A retractable is the right buy when you open the bed many times a day, want it locked whenever you walk away, and don’t mind giving up 7–14 in of bed. If that’s not you: - **Want full bed access and hard-cover strength for less?** A hard folding cover such as the [BAKFlip MX4](https://truckcoverguide.com/tonneau-covers/bakflip-mx4/) (about $1,200 for the F-150) stands upright behind the cab and opens nearly the whole bed, but it’s only as secure as your tailgate lock. - **Want roll-up convenience without a canister?** The [BAK Revolver X4s](https://truckcoverguide.com/tonneau-covers/bak-revolver-x4s/) rolls aluminum slats into a drum at the cab and leaves the floor clear, for about $1,500. - **Want the most security and sealing?** A one-piece lid like the [UnderCover Elite](https://truckcoverguide.com/tonneau-covers/undercover-elite/) has a key lock and, on its sibling SE, was almost entirely weatherproof in Car and Driver’s test. You can’t haul tall cargo with it, though. Our [tri-fold vs roll-up vs retractable](https://truckcoverguide.com/posts/tri-fold-vs-roll-up-vs-retractable/) guide goes through those trade-offs in detail, and the [cover matcher](https://truckcoverguide.com/tools/cover-matcher/#security=3&access=most) filters every line by the security and access you need. ## How we chose We track three retractable lines and compared them on the same data: slat material, canister depth, load rating, lock type, warranty, install notes and the Amazon price for the trucks we checked. Scores weight security and build at 30%, weather sealing at 25%, bed access and usability at 25%, and value at 20%. The RetraxPRO MX scores 7.4, and the RetraxONE MX and Roll-N-Lock M-Series 7.3 each. The PRO leads on security and warranty; the Roll-N-Lock leads on bed space; the ONE leads on price. None scores high on weather sealing, because no hands-on test we found shows a retractable staying dry. The full method is on [how we research](https://truckcoverguide.com/how-we-research/).

For most owners, the RetraxPRO MX: aluminum slats rated for 500 lb, a key lock that holds the cover at any point along the rails, and a lifetime warranty, at about $1,917 for the 2021–2026 F-150 5.5 ft bed. The RetraxONE MX is the cheaper alternative if you don't load the cover, and the Roll-N-Lock M-Series leaves the most bed space. ### How much bed space does a retractable cover take? The canister sits on the bed floor at the cab end. Roll-N-Lock says its M-Series canister is 7-1/4 in deep. The retailer etrailer lists the RetraxPRO MX canister at 13-1/2 in deep by 12 in tall. On a 5.5 ft (67.1 in) F-150 bed that leaves roughly 89% and 80% of the bed length open. ### Do retractable tonneau covers leak? Some water usually gets in. Car and Driver's hands-on test of a GatorTrax retractable found leaks at the cab-side corners and water pouring from the canister until a drain tube was fitted. Retrax and Roll-N-Lock both route drain tubes from the canister through the bed's drain holes; install them carefully. ### Are retractable tonneau covers worth the money? They are if you open the bed many times a day and want it locked whenever you walk away. A retractable slides open with one hand and locks with a key at any position. If you open the bed a few times a week, a hard folding cover such as the BAKFlip MX4 costs about $700 less and opens the full bed. ### Do retractable covers need drilling? Usually not for the rails, which clamp in. The drain tubes route through the bed's existing drain holes, but a spray-in bed liner can cover those holes: etrailer's installer had to drill through a spray-in liner to fit a RetraxONE MX. ## Sources - [Car and Driver: Best Pickup Truck Tonneau Covers of 2026, Tested](https://www.caranddriver.com/car-accessories/best-tonneau-covers-tested/) · checked 2026-11-12 — Its tested GatorTrax retractable leaked at the cab-side corners and from the canister, needed a drain tube that requires drilling, and could only be locked fully closed or fully open. - [etrailer: RetraxPRO MX retractable tonneau cover (RT80384)](https://www.etrailer.com/Tonneau-Cover/Retrax/RT80384.html) · checked 2026-11-12 — Lists 1 in thick aluminum slats, a 500 lb evenly distributed rating, a 13-1/2 in deep by 12 in tall canister, built-in drain tubes and a limited lifetime warranty. - [etrailer: RetraxONE MX retractable tonneau cover (RT60462)](https://www.etrailer.com/Tonneau-Cover/Retrax/RT60462.html) · checked 2026-11-12 — Lists polycarbonate slats with aluminum I-beams, a 200 lb rating, a -50°F to 200°F temperature range and two drain tubes. - [Amazon: Roll-N-Lock M-Series XT for 2021–2024 Ford F-150 5'7" bed (131M-XT)](https://www.amazon.com/dp/B09N9TRSM5?tag=truckcoverguide.com-20) · checked 2026-11-12 — Maker copy says Roll-N-Lock canisters are the most compact of any retractable at 7-1/4 in deep, and that the XT's MaxTrak rails accept most T-slot accessories. - [Amazon: RetraxPRO MX for 2021–2026 Ford F-150 5'7" bed (80378)](https://www.amazon.com/dp/B08L46PC1S?tag=truckcoverguide.com-20) · checked 2026-11-12 — Listed at $1,917.02 with a 500 lb rating, keyed lock at any position and a lifetime guarantee. ## Get new guides by e-mail One short e-mail when Truck Cover Guide publishes a new guide.
