This is the Avenger A4050CS Junior Boom Stand. Used as a stand, the maximum height is 16.4' (5 m). When the 2 section boom is in use, its maximum length is 8.75' and its maximum load is 17.7 lbs -- strong enough for a medium sized light fixture with a softbox or umbrella.
This stand has a leveling "lazy" leg which extends to stabilize the load on uneven terrain. This item replaces old catalog #A700.
