The Kupo Master C-Stand 40-inch Riser Sliding Leg Kit - Black, 10.6-ft is an ideal tool for mounting lighting equipment, along with a wide range of light-shaping tools and accessories. In addition to the C-Stand, this kit includes a 40-inch grip arm and a 2.5-inch grip head. The C-Stand, which has a sliding base, features two spring-loaded legs that open in fixed positions and a third leg that is height-adjustable. To alter the height of the third leg, loosen the locking knob and slide it down or up, toward the main riser section. This height flexibility lets you use the stand on stairs, uneven terrain, or an incline. Use the grip arm and grip head for keeping lighting fixtures in position whenever they are placed at the end of the arm.
