This kit includes (4) feet -or- legs and a load bar set, ie. two bars. Additional components can be purchased here.

The K9 Load Bar System from Eezi-Awn is a revolutionary advancement in expedition-style roof management and storage; it is thinner, lighter, stronger, quieter, more functional, more aerodynamic, more durable, and more aesthetically complimentary to your vehicle than the competition. They are powder-coated aluminum with a 8mm T-Slot on both top for attaching equipment. There is a rear lip on the load bar, making it easy to drill and bolt down soft shell or hard shell roof top tents or other equipment.  The slot on the bottom of the extrusion holds the Eezi-Awn DIY rectangular extrusion which captivates the head of a M8 bolt and allows it to position anywhere in the length of the K9 Load Bar for attachment to feet or legs.

The K9 Toyota Bed Rail Leg was designed specifically to saddle the top of the bed rail, while attaching to the under rail factory supplied channel with a threaded mounting plate and 2 bolts.  A pair of K9 Load Bars are then attached to the top of the legs, providing plenty of support for most any gear you want, including roof top tents.
