CURT Jeep roof rack crossbars make your Jeep Wrangler JK ready for any adventure. They quickly clamp onto the roof and create an entirely new storage space for a wide variety of cargo. The unique feature of these cargo brackets is their quick-release clamps. The ends of each bracket are equipped with a gutter clamp that securely mounts onto the roof gutters whenever needed. The brackets can then be loaded with a cargo carrier, basket, kayak racks or other items. The clamps are constructed from powder-coated steel for maximum strength, and they help keep your cargo fully secure no matter where the trail takes you. When the adventure ends, the brackets can easily be removed by simply pulling clamp latches. CURT Jeep roof rack crossbars also have a fully slotted channel. The slots can accept bolts or hardware from a roof rack cargo carrier or any number of straps, ropes or bungees. With multiple slots spanning the length of the bracket, straps can also easily be adjusted. CURT Jeep roof rack crossbars are rated for a maximum capacity of 150 lbs. They come with all necessary hardware and require no drilling or vehicle modification for installation. They are designed to fit the Jeep Wrangler JK (compatible with hardtop only). Two brackets are included per package.
