The Kupo KCP-610 is a steel fork designed to secure foamcore or polystyrene boards. The end featuring the steel spikes stabs into the foamcore or polystyrene, while the end featuring the 5/8" spigot secures the fork to gripheads or anything else with a 5/8" receiver. It is extremely handy for smaller foamcoare or polystyrene boards (not full size 2.4m x 1.2m).

Foamcore and Polystyrene are commonly used to bounce (reflect) light. When painted black, the board are used to cut (block) light.
