The Bogen 2915 Super Clamp is made of lightweight cast alloy.  The Super Clamp is a very versatile tool and it holds just about anything: cameras, lights, umbrellas, hooks, shelves, plate glass, cross bars, even other Super Clamps.  In turn, the Super Clamp can be securely mounted on any tube from 0.5" to 2.1" and is supplied with a unique wedge insert for clamping onto flat surfaces.  A built-in socket allows the use of over 30 attachments to hold anything from backgrounds to lighting fixtures.

The Bogen Standard Stud (2908) is included.
