The same great quality of the PowertraxPRO, now comes in a powerful matte black powder coat finish. We've powered up the best bed cover on the planet. This retractable bed cover features all the same great benefits of the RetraxPRO MX, but allows for hands-off operation via a wireless remote control. The PowertraxPRO MX features unbeatable aluminum construction that stands up to the toughest conditions. Once you have the PowertraxPRO MX installed, you'll never have to worry about your bed cover again. The PowertraxPRO MX locks in any position using an electromagnetic brake -- the perfect way to keep the contents of your box safe. Plus, it allows for unlimited flexibility in hauling almost any object. The retractable cover opens and closes easily with one hand thanks to its sealed-for-life bearings. There's no need for pull straps, Velcro, snaps or springs.
