The Leofoto LBQ Series Leveling Base with Butterfly Handle acts like a half ball, providing +/-20° of leveling range capability. It locks easily and securely in position with a twist of the large butterfly handle at the base of the ball. This leveling base mounts on the apex of LG/LQ Series tripods via the adapter but also has a 3/8″ mounting socket in the base to be mounted on any tripod with a 3/8″ mounting stud.
