The RetraxONE MX retractable truck bed cover is part of the Retrax® Polycarbonate Series line, featuring rigid aluminum-reinforced polycarbonate construction for superior impact resistance and durability. Due to polycarbonate’s exceptional UV resistance, the RetraxONE MX offers unparalleled operation in extreme temperatures, ranging from -50 to +200°F. A resilient matte black powder coat finish provides incredible abrasion resistance and subtle styling.

Unlike the competition, the RetraxONE MX features a one-piece polycarbonate construction, engineered without leak-prone joints, hinges, or moving mechanisms. This truck bed cover features a patented low-profile design that streamlines its appearance while providing superior protection. Its low-profile design also ensures maximum visibility out of the rear window.

The compact canister features a unique spiral track system that prevents abrasions and scuffs as it opens and closes. The operation of this cover allows it to remain flush against the bed rails, creating a dependable seal to keep the elements out and protect your cargo. If water leaks into the canister, integrated drain tubes funnel water outside the bed to keep your valuables clean and dry.

The RetraxONE MX employs a maintenance-free sealed ball-bearing roller system that glides effortlessly along the side rails. A convenient handle eliminates the need for pull straps, Velcro, snaps, or springs. The RetraxONE MX is key-lockable in any position, providing unlimited flexibility while hauling cargo. The cover can support up to 200 pounds evenly distributed for extra cargo capacity in a pinch.

  • Failure to adequately secure cargo to prevent damage to the Retrax cover

Conditions and Limitations
This warranty is subject to certain conditions and limitations
including, but not limited to, the following:

  • Any part of a Retrax retractable pickup bed cover that is found to be defective under the terms of this warranty will be repaired or replaced, using either new or reconditioned parts, at the discretion of the manufacturer.
  • In determining what constitutes a failure under the terms of this warranty, the decision of the manufacturer will be final.
  • This warranty is applicable to the original purchaser only and is not transferable to subsequent purchasers.
  • The manufacturer does not accept any responsibility in connection with the installation of any of its products by its dealers or agents.
  • Without regard to an alleged defect of its products, the manufacturer does not, under any circumstances, assume responsibility for inconvenience, loss of time, revenue or other consequential damage including, but not limited to, expenses for telephone, food, lodging, travel, loss or damage to the vehicle the products are installed on or loss or damage to personal property of the purchaser or user of the products.

Care and Maintenance
The Retrax bed cover should slide open and closed easily. Do not force the cover open or closed. Please call Retrax at (800) 206-4070 before attempting any maintenance or repairs.

Care should be taken when setting any items on the cover. If the cover is dusty or an item is dragged across the cover, scratching or hazing may occur. Treat your Retrax bed cover like the hood of your pickup. Do not wipe dust off the cover; it should be washed off.

With proper care, the polycarbonate cover will last for many years. It should be cleaned with mild soap and water. Do not use any strong chemicals or cleaners of any kind. Do not allow gasoline to come in contact with the cover.

Every effort has been made to make the Retrax weathertight; however, the Retrax is not waterproof. Use extra care to prevent damage to items during severe weather conditions or while entering a car wash. Water may collect on the cover; remove water before opening.

Do not force your Retrax open if ice forms on your bed cover after an ice storm or car wash. You should use your hand to tap around the perimeter of the cover, which should free up the weather stripping that seals the bed cover along the edges.

Lock de-icer can be used to free up the key lock. Do not allow de-icer to make contact with the bed cover. Dry graphite can be applied to the lock assembly to help prevent freezing.

Some states do not allow limitations on how long the implied warranty lasts, so the aforementioned limitations may not apply to you.
