The black, 19-28" Baby Adjustable Offset Arm from Kupo is a handy piece of grip gear to have on the set. Ideal for hanging lights over a wall or obstruction, the metal arm telescopes from 19 - 28" or anywhere in between and locks down with a sturdy T-handle. The arm has a 5/8" receiver for the light stand and two 5/8" spigots for the lights.
