Pace Edwards created the Elevated Truck Rack to allow you to carry larger cargo while being able to utilize your UltraGroove tonneau covers. The way this works is by mounting to the RES rail expansion system built in to the UltraGroove, UltraGroove Metal, and UltraGroove Electric truck bed covers. The four high towers have feet that mount into the RES channels for fast, secure installation without any drilling needed. The two crossbars are made by Thule and accept a wide variety of products so you can haul things like kayaks, surfboards, and other larger cargo with ease. The quality materials will withstand the abuse while being able to carry up to 200lbs. Pace Edwards engineers the Elevated Truck Rack in the USA so you know this product is made to the highest standards. | Pace Edwards Elevated Truck Rack ELF0301
