Keeping tools or gear safe in the bed is a big deal. The RetraxONE MX solves that with a locking handle you can secure at any point along the rails. Once closed, it locks flush with the cover and stays hidden under a flat lid that shields the keyhole from dirt and moisture. When paired with your locked tailgate, it’s tough to beat for keeping cargo out of sight and protected from theft.
You don’t have to wrestle with straps or snaps every time you need to open the bed. The RetraxONE MX slides open with one hand using sealed ball-bearing rollers that never need lubrication. The cover glides evenly without binding or twisting, and the spiral track inside the canister keeps the panels from rubbing together, so it stays smooth and quiet each time you roll it open or closed.
Built from Lexan polycarbonate with 5/8" thick aluminum I-beams embedded every 4-3/4", this cover is tough enough to handle up to 200 lbs of evenly distributed weight. It holds up through heat, snow, and ice—from -50° to 200°F—without cracking, swelling, or fading. The matte black finish resists scratches and UV damage, while weather stripping and foam seals keep out rain, snow, and dust.
When rolled up, the cover disappears into a compact canister that sits at the front of the bed. The angled bottom design leaves extra room underneath for tools or smaller gear. Two included drain tubes route water out through factory holes, keeping the inside of the canister dry and mildew-free.
The side rails sit just 1" above the bed for a flush, streamlined look that blends in without bulk. Everything clamps on—no drilling required—and the rails align easily for a tight, even fit. Once installed, you get a simple, low-profile cover that improves aerodynamics, keeps weather out, and stays maintenance-free.
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.
