The BASE Rack takes accessories and cargo loading to a whole new level of simplicity, speed and personalization. The Light Bar Mount adds to the broad range of attachment options and is required when mounting ARB BASE Rack LED Light Bar (PN 1780500) with the BASE Rack front section guard rail in place. The mount consists of a left-right pair of powder-coated steel brackets that attach to the dovetail section of the BASE Rack. By incorporating a dovetail extrusion around both the full perimeter and along each edge of the internal beams, the BASE Rack provides endless mounting and attachment options. Adding, removing and repositioning accessories and roof loads is quick and easy with the BASE Rack's dovetail system, making it easier to install and remove individual items without disturbing the whole load. Plus, unlike traditional roof rack channels, the BASE Rack dovetail extrusion won't collect dust and debris. ;
