Rack Systems' modular design allows a universal tray to be installed in multiple locations around your Jeep -- the versatility to put storage where you want it. Depending on where they're installed, trays can each hold up to 200 pounds of gear. The thermoformed plastic tray is lighter than steel and has better impact resistance. Rounded corners help prevent injury if bumped. Cargo is tightly secured with tie-down straps anchored by installed I-bolts.
