The Kupo CL-30MK C-Stand with arm, grip head and sliding leg allows you to enjoy a quick-release set-up and a sliding leg for sloping or uneven ground. Simply unlock the knob on the longer leg so that all legs can be moved into the correct positions in seconds. While the longer leg is doing a levelling job and the spring-loaded positioning pin is engaged, then the middle leg is able to hold in place preventing tipping from the accident. Used alone or in combination with a grip head and a grip arm, the C-mount is used to mount lighting equipment and a whole variety of light shaping tools and accessories. The three center column sections have respective diameters of 25, 30 and 35 mm.
