The Kupo Convertible Junior Boom Stand is an incredibly versatile support that can be converted from a standard light stand to a junior boom arm by simply pulling the center column out of the stand and using the pivoting collar to position the arm. Constructed from chrome plated steel and featuring square-end legs, the boom arm can support 66lbs at it’s minimum extension of 5ft and 17.6lbs at it’s maximum extension of 9ft. Perfect for a medium sized light fixture with a softbox or umbrella attached.
