The Rhino-Rack Backbone is an interior structure set up on the inside of the JEEP JK Wrangler 4 door. 3 plates on each side of the JEEP's Hard Top are connected with the interior frame extending your roof line to carry heavier loads.
The Rhino-Rack Backbone is a mounting system for your Toyota FJ Cruiser. Connecting to your vehicle's roof via 3 bases on each side, it allows for a Rhino-Rack Pioneer System to be fitted on top.
The Quick Mount Ditch Bracket provides a permanent or fixed mounting point for the roof rack to attach to. It can only be used in conjunction with the RLT600 Quick Mount leg.
