The Mako Aero's form fitting cradle fits any hull shape. Dynaflex™ pads flex to grip the boat hull securely. Includes bow/stern tie down straps for complete kayak stability. A soft polyester pad with a self adhesive back attaches to the saddle protecting the finish on your boat. Compatible with round, square and some factory crossbars out of the box, also works with Mighty Mounts (sold separately) to fit a wider range of factory racks. Sold in pairs. One pair supports 1/2 of your boat, front or back.
