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 supplied jubilee clips. The clips are sufficient diameter so that these mounts can be used on an FIA specification roll-cage. 
 
NOTE: Does not include the camera, nor the clamp body and rubber strap that attach the camera to the mount.
 
The camera clamp itself comes supplied with the suction mounts contained within a VBOX Video HD2 standard package - however they are also available as separate items.
