This J-style kayak roof rack folds down when not in use, saving overhead clearance and reducing wind resistance. Made from anodized aviation-grade aluminum, it mounts to square and oval factory cross rails on cars, SUVs, and trucks. The oversized rubber saddles and padded uprights protect your kayak from rubbing and damage during transport. Four heavy-duty straps with 750 lbs break strength are included, along with two paddle holders for convenience.
