The height- and width-adjustable Elevate Outdoor Aluminum Truck Rack is designed for no-drill, easy-install convenience. The lightweight aluminum rack accommodates cargo or varying sizes up to 800 lbs. evenly distributed across both bars. Use the four adjustable-width ladder stops to secure items to the rack. This truck rack installs with J-clamps so that drilling into your truck is not necessary. It fits pickup truck beds between 44” to 66” wide, and the top bars have an adjustable height range of 27” to 33.5”. The rack assembles easily and is simple to remove when not needed.
