Some covers jam, bind, or need constant adjustment to stay smooth. This one doesn’t. The RetraxONE MX uses sealed ball-bearing rollers that glide along the rails without lubrication or springs to fail. You can open or close it with one hand using the pop-up locking handle, and latch it at any point along the rails when you need partial bed coverage. When it’s rolled up, the cover stores neatly inside a space-saving canister that keeps it protected and out of the way.
Keeping tools and supplies dry and secure can be tough when rain or snow hit. The RetraxONE MX seals your truck bed with weather stripping and foam gaskets on all sides, plus an overlapping tailgate lip to block out water and dust. The flush-mounted locking handle sits flat against the cover under a protective lid, keeping it hidden from sight and safe from corrosion. Lock it closed with your tailgate latched and your cargo stays secure and out of view.
The cover is built from high-strength polycarbonate (Lexan) reinforced with 5/8" thick aluminum I-beams spaced every 4-3/4". It supports up to 200 lbs of evenly distributed weight while resisting dents and impacts from tools or debris. Designed to perform between -50 °F and 200 °F, it won’t crack in extreme cold or warp in heat. The matte black finish is UV-treated, scratch-resistant, and stays cooler to the touch than metal on hot days.
Water that gets inside the canister drains out through two included tubes rather than pooling or causing mildew. The spiral track system prevents the cover from rubbing on itself as it retracts, reducing wear over time. The canister’s angled bottom leaves extra space underneath for long items so you keep more usable bed room even with the cover installed.
Side rails sit just 1" above the bed for a streamlined appearance without bulky edges. The flush top panel overlaps the bulkhead for a smooth line front to back. Once installed using simple clamp-on rails—no drilling required—the RetraxONE MX gives your truck a sleek look while adding year-round protection and convenience.
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
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.

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.

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.
