This hard coat anodized aluminum and stainless steel clamp can be quickly attached to a tank lip by one person without the use of tools. The mount and jaws can be moved to any of the 42 positions on the backbone for maximum versatility. Detented pins hold the mount and jaws in place and a travel stop keeps the pins attached to prevent them from being dropped or lost. Once the clamp is attached the Hemisphere monitor is secured to the clamp by sliding the socket at the base of the monitor over the mount. The clamp arm and fixed end can be removed and the backbone can be inserted into any standard 2" (51mm) hitch giving the ability to quickly add a monitor to most vehicles without costly modifications.
