Can be quickly attached to round and various other odd shaped objects by one person without the use of tools. Mount and chain blocks can be moved to any of the 42 positions on the backbone for maximum versatility. Detented pins hold mount and chain blocks in place and travel stops keep pins secured to prevent them from being dropped or lost. Once clamp is attached, a Hemisphere monitor is attached by sliding the socket at base of monitor over the mount. Chain blocks can be removed and backbone can be inserted into any standard 2" (51 mm) hitch giving the ability to quickly add a monitor to most vehicles without costly modifications.
