This is a versatile aluminum bracket that will fit on almost any light stand. It includes two removable, reversible studs to adapt to light stands with top studs smaller than the standard 5/8 inch. Transfers the weight of your softbox to its speed ring, relieving your light head, and providing better balance atop a light stand. Bracket tilts and swivels to make aiming the light or flash easy. Has a locking umbrella socket that will accept umbrella shafts up to 3/8 in diameter.
