The integrated aluminium rods and sliders will be bolted to your bikebox which in turn will fix to our unique aluminium roof bar brackets. The brackets include quick release skewers, secured by a pin to prevent movement in transit, this means that the box can be removed from the car without you having to open the bikebox or mess with your bike.

The system can be retro fitted but it will require the user to do some drilling and fix the t-bars to your box using the nuts & bolts provided.
