The rack consists of 2 laser cut side rails constructed of 3/16" 5052 aluminum plate. These rails have 3-4 mounting tabs each that will allow you to bolt the rack to the Thule/Yakima tracks using the appropriate harware. This design allows the addition of this roof rack without drilling or modification to your vehicle. The crossbars are made from a 2" x 1" aluminum extrusion that has a single top facing T-SLOT channel. This offers numerous solutions for tie down options, cargo security, and the addition of accessories such as tool mounts or lighting. The rack comes shipped with a powdercoated finish.
The rack is completely modular in that you choose how your rack is configured. You can also choose the number of cross bars you assemble your rack with. The short bed rack comes standard with 6 cross bars for cargo. The long bed rack comes standard with 7 cross bars.
Weight capacity of the racks varies based on the number of crossbars used and their configuration. We expect all consumers to use good judgement and common sense with the loads they plan to carry using these rack systems. The Toprac is limited by the weight capacity of the topper. Please consult the manufacturer of your topper for guidelines and capacities regagarding the load capacity of your individual topper.
