Safely mount lighting fixtures on a wall and keep your studio free from stands with the all-metal WB-100 Triangle Wall Mounting Boom Arm from Neewer, available here in a black finish. This wall boom includes four expansion bolts, allowing you to mount it on solid concrete walls. The boom arm has a maximum load capacity of 6.6 lb and extends from 21.7 to 45.7" for flexibility. In addition, the WB-100 features a reversible 1/4"-20 to 3/8"-16 adapter screw for wide compatibility. Its 180° range affords great adjustability, and collapse it flat against the wall when it's not in use.
