The roll cage mount has a solid aluminium body, connected to a curved mounting plate that is bolted to the bar via a pair of jubilee clips (2 supplied) or worm drive hose clips (four supplied). The clips are sufficient diameter so that these mounts can be used on an FIA specification roll cage. The kit also contains a strip of protective rubber to stop the roll bar from being scratched. NEW: A locking nut has been added to facilitate the fastening of the camera/display.
