The Apex extra-large steel roof cargo basket provides the extra space you need when you've got a lot to haul. Made from durable steel that has been powder coated for rust protection, this large roof rack carries up to 150 lbs. using the existing crossbars on your vehicle. The cargo rack's universal U-bolts can accommodate square cross bars up to 3-1/4" wide x 1-3/8" thick or round bars up to 1-3/8" in diameter. Easy to assemble and install, this roof rack also includes a steel wind fairing to reduce wind noise and resistance. Optional roof bars may be attached to the top of the basket, allowing you to use roof-mount accessories in addition to the luggage basket.
