The Manfrotto 035RL 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.

 

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 Standard Stud (2908/03614) is included. This item replaces old catalog #2900.
