The Kupo Convi Clamp with Adjustable Handle Silver comes with a hexagonal receiver that helps in attaching most Convi accessories. Its lightweight alloy construction is more durable and long lasting. From a simple stud to the versatile Max Arm, this wonderful clamp helps in mounting almost any light fixture, camera or accessory. The advanced feature of this clamp is the ratcheted handle that is convenient to operate. It lets you reposition the handle whenever enough space is not available to rotate in a complete circle while tightening or loosening the clamp. Providing more safety to the Convi accessory, its spring locking safety system holds the clamp even when the locking screw fails to hold.
