The PowertraxONE MX offers excellent security and protection for the items in your truck bed. This tonneau cover can withstand impacts and inclement weather, and it can perform in temperatures between -50 and 200 degrees F. It won't swell in the heat, contract in the cold, or crack in ice storms, unlike some other tonneau covers out there. When your arms are full of groceries or supplies, you can open this electric tonneau with the touch of a button for fast, easy access to your truck bed. You can also use the remote key fob to secure the cover at any point along the rails for hauling flexibility.

Electric, Retractable Operation with Key Fob

Retrax sealed ball-bearing rollers

This tonneau cover retracts quickly and easily for complete truck bed access. It does this by gliding along the side rails with sealed ball-bearing rollers, which also prevent the cover from binding or retracting unevenly. The PowertraxONE MX has no joints or hinges that can wear out, freeze, or trap dirt. It does not need to be lubricated and it has no springs that can fail. Unlike other truck bed covers on the market, you won't have to struggle with pull straps, hook-and-loop fasteners, or snaps every time you open and close the cover.

Retrax key fobs

Two key fobs are included so you can operate the cover with the touch of a button. The wireless remote function is great for when you're approaching your truck with your hands full and you can't reach out to manually open the cover or your tailgate. Simply press and hold the "O" button to open the cover or press and hold the "C" button to close the cover over your cargo.

Retrax stops part way

You can also stop the cover at any point along the rails by simply releasing the Open and Close button. An electromagnetic brake will stop the tonneau and lock it in place. This way you can carry long items that overlap your tailgate while still covering cargo, such as a tackle box, that's stored closer to the bulkhead of the truck.

Retrax spiral track system

When not in use, the cover rolls up into a space-saving storage canister at the bulkhead of your truck, so you'll never have to remove the tonneau to access your cargo. This canister has a unique spiral track system that keeps the cover from coming into contact with itself while it's retracted. This helps prevent wear and tear on the cover while you're opening and closing it.

Retrax canister is small

With the cover fully retracted, the entire canister assembly only takes up a small portion of your truck bed. And the angled bottom of the canister gives you more space to slide long items or small gear underneath it.

Maximum Security and Protection for Your Cargo

Retrax key fobs on cover

When the PowertraxONE MX is closed, potential thieves will find it nearly impossible to access the items in your truck bed. Only the key fobs can unlock the tonneau, and there is no way to retract or extend the cover without them.

Retrax tailgate open

This cover is better at preventing cargo theft than soft covers, which can be cut open with a knife. It also cannot be pried up at the edges like some hard, folding covers. As a result, your cargo and truck bed are secure when this cover is closed, as long as you lock your tailgate as well. Conveniently, the cover operates independent of the tailgate, so you can open and close the tailgate without touching the cover, and you can open and close the cover without disturbing the tailgate.

Retrax built in light

Thanks to the built-in LED light, you can also protect your cargo from prying eyes while you search the truck bed for your gear. This integrated cargo light is located on the storage canister by the driver's side. To illuminate the cargo light, simply press the light-symbol button on the key fob. Press the button again to turn off the LED. If you forget to turn off the light, a timer will automatically shut it off in 3-5 minutes, so it won't drain your battery.

Retrax weather strip

To keep snow, water, and dust out of your bed, the tonneau cover includes weather stripping and foam seals. An automotive-grade weather strip ensures a firm, dependable seal along the bulkhead of your truck. Attached to the bottom of each side rail is a foam seal that conforms to the shape of your bed rails. These seals help to prevent any scratches on your bed rails as well as fill any gaps to keep your cargo from getting wet or dirty. The cover also overlaps the top of the tailgate for additional protection against intrusive dirt and debris.

Durable, Long-Lasting, and Attractive Cover

Retrax attractive cover

The PowertraxONE MX is constructed of a polycarbonate known as Lexan, the same material used to make bulletproof glass and jet fighter canopies. It has excellent dent and impact resistance to keep it from getting damaged by falling debris. Additionally, 5/8" thick aluminum I-beams are embedded into the polycarbonate every 4-3/4" to give the cover added strength. As a result, this cover can hold up to 200 lbs of snow or evenly distributed weight when it's rolled out.

You'll never have to worry about the cover cracking in the cold or bubbling or fading in the hot sun because it's designed to perform in temperatures from -50 and 200 F, and its hard thermoplastic is UV treated to protect it from fading. On hot summer days, Lexan is cooler to the touch than metal, so you won't get burned when accessing your gear. And on top of that, its durable matte black finish is weather and scratch resistant.

Retrax drain tube

To prevent mildew from forming on the cover while it's rolled up, the PowertraxONE MX features a water management system that channels excess water out of the storage canister. Two drain tubes attach to the bottom of the canister to remove any water that gets inside. The tubes then route water through the existing drain holes in the floor of your truck bed, ensuring that the stored cover remains as dry as possible.

Retrax flush design

When rolled out, this tonneau sits nearly flush with the back of the canister to give a streamlined look. The sleek frame features a top panel that overlaps the bulkhead of the truck and storage canister, eliminating the gap in between.

Retrax extends over 5th wheel

The low-profile side rails mount just 1" above your truck bed, which offers a sleek look while still providing enough clearance for most 5th-wheel hitches to remain installed beneath the cover.

Simple Installation

Retrax installation parts

To install the tonneau cover, begin by attaching the side rails to the canister with the provided screws.

Retrax installation

Because the cover comes preinstalled inside of the canister, it will take 2 people to lift the assembled unit and place it on your truck. Once the cover is in position, make sure that the side rails are square on your truck bed rails. Then secure them in place with the bolt-on clamps. Install the drain tubes in the canister and route them through the factory holes in your truck bed.

Retrax powered canister

Run the wiring harness up to your truck's battery per the included instructions. Then plug the truck bed end of the harness into the power connectors on the driver's side of the motorized canister. Lastly, connect the ring terminals to your truck battery for power.

Video Transcript for Manufacturer Installation of the Retrax Tonneau Covers

Connect the front cover below the rails, using the front cover mounting screws. Pull the protective film off the spiral canister. Apply the rubber washers to the drain tub fittings, and connect the drain tubes to the 1/2" holes located on the bottom of the spiral canister. Once you've assembled the Retrax cover, two people should work together to lift the cover onto the truck bed. Once the cover is in place, insure that the weather strip on the front of the cover is laid out properly on top of the bulkhead of the pickup, pointing toward the cab. Close the tailgate, and using the measurement tool that is supplied, measure 1/8" between the bottom notch of the rail and the inside face of the closed tailgate.

Next, install the clamps. Start with the locations closest to the canister. The clamps are mounted between the rail adjustment screws. Then attach the rear set of clamps. Once the cover is secure, direct the drain tubes so that they drain water out of the truck bed. Drain holes vary on different makes and models of trucks.

Once finished, open and close the cover, making sure that it is rolling without binding. If needed, turn the rail adjustment screws so rails remain parallel. Pull off the protective film, and double-check that the keys and lock work properly. Now that the Retrax Retractable Bed Cover has been installed, you're ready to take it out on the road.

Review from a similar PowertraxONE MX Tonneau Cover in Tonneau Covers

Super good product. It was easy to install and came with all the hardware. The remote is really good for closing or opening it from the cab while driving if it starts raining. Travels smooth inside the rails. Nice drainage system for rain and car washes. The seals are good. No water in the bed ever. Covers my expensive 5th wheel hitch from dirt and moisture. I like the poweder coated finish. The motor drives the cover back and forth easily. The rigid cover has seen hail and it just bounces off. No marks, dents or dings. Awesome product for truck bed protection.
