Kupo KCP-612 adapter and accessory kit for 1-1/2″ arms and tubes is designed primarily for the boom set to hold the lighting in the desired position, keeping the stand out of the frame in the safest method. It works with a standard 1-1/2″ schedule 40 (48.3 mm) tube. The front adapter of the kit has 2 pins and 1 junior receiver that allow you to mount lighting fixtures or other gripping accessories such as a flag or frame. The rear adapter is also welded with 2 hooks for hanging on sandbags to increase the stability of the arm and a D-ring for connecting the ratchet strap to the D-rings of the front adapter and the centre adapter, which are mounted on the head of the grip. The junction tube adapter is equipped with two knobs for secure mounting when connecting the tube from two sides. It has a unique locking knob that prevents the knob from coming off even if it is completely unscrewed. A safety wire with Linchipin is attached for an additional level of safety.
