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. The Junior Boom Stand is also equipped with one leveling leg for balancing loads on uneven terrain, making it just as at home in the field as it is in the studio.
