An aluminium cross arm that turns a single light stand or tripod into a platform for several accessories. It carries two top mounts and two side mounts — one 1/4"-20 and one 3/8"-16 at each position — so a light, microphone, monitor, tripod head or laptop shelf can share one stand instead of each needing its own. The tube slides to rebalance the load and locks with ratchet levers, as do both top mounts. Light and compact enough to travel, and a genuine space-saver on a crowded set.
