Kupo 40" Master Riser C-Stand Sliding Leg Kit (Silver, 10.6') has two legs that are spring loaded to open in fixed positions, while the third leg is height adjustable by loosening a locking knob and sliding it up and down the main riser section. This enables the user to raise one leg higher than the others to level out the stand on an incline or uneven terrain.
The 40" Grip Arm with Hex Stud is a 2 1/2" grip head mounted on the end of a 40" 5/8"-diameter steel rod finished with a faceted hex stud to keep lighting fixtures in position when they are placed on the end of the arm. The surface of the tubing is stippled to create a rough texture to ensure a non-slip surface. The 2-1/2" grip head consists of a pair of rotating aluminum discs attached to a 5/8" (16 mm) receiver. The discs have four different sized "V" shaped jaws to accept any accessory with a 5/8", 1/2", 3/8" or 1/4" mounting stud or tubing. The V-shaped jaws have teeth that grab whatever is mounted between the plates securely. The 2-1/2" grip head features an oversized ergonomic T-handle and dedicated roller bearings designed for maximum torque. This kit includes a stand, 2.5" grip head, and 40" grip arm with hex stud.
