Bestop's new Rack Systems provide you with convenient overhead storage for open-air driving. 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. The Hinged Roof Rack is is contructed of 1-1/2" diameter black, powder-coated tubular steel that attaches to windshield hinge and rear frame. It remains stationary while switching and converting tops and mounts up to 3 Universal Rack Trays (sold separately). Each tray holds up to 75lbs. Hinged Roof Rack is a no-drill installation.
