The Convi Clamp is more than just an amazing clamp it's the foundation of an entire grip system. The all-metal Convi Clamp is made from a lightweight alloy that will support loads of up to 44lbs (20kg). It features a hexagonal receiver that accepts dozens of Convi accessories from a simple stud to the versatile Max Arm to mount almost any light fixture camera or accessory. The receiver features a spring locking safety system to ensure that the Convi accessory won't separate from the clamp if the locking screw loosens unexpectedly. The Convi Clamp has a jaw that will extend from 0.2"-2.0" (5-51mm) in diameter. It also features a saddle to securely mount it on flat surfaces. The Double Convi Clamp is a pair of Convi Clamps joined back to back with a double hexagonal stud. You can use a couple of Double Convi Clamps to join a whole variety of materials together such as a cross bar on a pair of Kupoles. It comes in a black finish.
