Product Details

ARB BASE Rack Under-Rack Light Bar Mount, suitable for attaching single bolt, end-mount light bars and work lights to the bottom of BASE Rack cross beams,

The BASE Rack takes accessories and cargo loading to a whole new level of simplicity, speed and personalization. The Underneath Light Bar Mount adds to the broad range of attachment options and is suitable for single bolt, end-mount light bars and work lights. The mount consists of a left-right pair of brackets that attach to the bottom of BASE Rack cross beams using an included stud plate and fasteners. It is suited for mounting small items up to 7.7lb per pair. 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.
