Rhino-Rack RTTB1 Backbone 2-Base Roof Rack Mounting System

The Rhino-Rack RTTB1 Backbone is a vehicle-specific roof rack mounting system that provides a solid foundation for installing a Rhino-Rack Pioneer Platform on your rooftop. Using 2 bases on each side, the Backbone connects directly to your vehicle's roof and delivers enhanced structural support and load distribution.

The stainless-steel Backbone system adds weight-carrying capacity and improves weight distribution, making it ideal for use with 3 or 5 under-bar Rhino-Rack Pioneer Platforms. Its sleek, aerodynamic profile minimizes wind drag and road noise, while a durable black powder coat finish blends cleanly with your vehicle's roofline.
