"Gain more length in your truck bed while keeping cargo contained with the Elevate Outdoors Truck Bed Extender. Designed to be used with the tailgate down, it adds up to 24"" of cargo space to your overall bed length so that longer items fit better and you have more room for transportation. Alternatively, it can also be installed deeper in the truck bed to provide a smaller, contained area for smaller items. The truck bed extender is manufactured from a strong, lightweight aluminum alloy with a black powder-coat finish. Designed to install and remove easily, it comes with quick-disconnect mounting brackets and all necessary installation hardware. During installation, the width adjusts to fit full-size trucks with a minimum interior width of 58.5"" up to a maximum interior width of 67.8"", both with and without bedliners (no cutting required)."
