The locking lever, which rotates around 360deg., enables the CB7.3 ball head to be quickly and securely fixed in any position. The position of the ball and of the horizontal axis can be reliably locked in one step. Equipped with the tried and tested Cullmann CX440 quick release system, the CB7.3 guarantees that the camera can be changed quickly and easily. The three built-in spirit levels ensure an exact alignment of the ball head. The CB7.3 is the ideal ball head for medium-sized DSLR cameras.
