The affordable SteelTop roof rack allows you to carry bikes, kayaks, ski carriers, roof boxes, and most accessories on the roof of your vehicle equipped with raised factory side rails. This complete roof rack system includes 2 steel square crossbars and 4 towers. These full-length crossbars extend past the towers to give you more mounting space for carriers. The towers have built-in locks to protect the rack from opportunity theft. The rack clamps onto your existing raised side rails and tightens down with the included tool making it simple to remove and re-install. Product workmanship and material performance is ensured with a Lifetime Limited Warranty. These carriers easily handle most sit-inside, and, sit-on-top kayaks. Features include a universal fit hardware package for round, square and oval cross bars. Kit includes 1/4" waterproof safety tie-downs and cam-style load straps. The J-Rack is covered by a One Year Limited Warranty which guarantees product replacement for materials or workmanship related problems. Please Note: The base of the carrier has a rectangular "cutout" that has been included for square cross bar fit. This "cutout" does not affect the fit or function of the carriers when installed to round or oval shaped cross bars.
