This is a Photoflex Multiclamp with Shoe Mount is a versatile 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. It also includes a shoe mount, which will accept virtually any shoe-mount flash unit.
NOTE: The flash shoe included with this product is only intended for use with flashes that have a knurled locking ring. For flashes that use a lever or other method of locking, it is necessary to buy an accessory flash shoe to replace the unit included with the clamp. The Stroboframe accessory shoe, catalog #300405, is recommended.
