Expandable Roof Racks (both the 2 and 3-Tower Racks) have base brackets allowing for easy mounting of 48'' aluminum extrusion/8020 (just like cargo racks on vehicles). We can provide the aluminum extrusion bars or you can source them yourself later. 

These bars allow you to mount virtually any off-road accessory. ROAM case mounts, slides, other racks - you name it. It's a versatile platform. 

Price includes all hardware and mounting
