Especially helpful when shooting video pans or multiple panoramic images, the Oben LH-2510 Leveling Base Head can tilt 10° in any direction and hold up to 25 lb. It can be placed between a tripod and a head to allow you to level your camera without readjusting the tripod's legs. A bullseye bubble helps ensure that your base is level to the horizon, and a ratcheted knob adjusts friction and locks the base.
The LH-2510 is 2" high, and weighs 11 oz. It has a base diameter of 2.5" and a top platform diameter of 2.75". The bottom of the base has a 3/8"-16 female thread for attaching to the tripod and a 1/4"-20 male threaded stud on top for mounting a camera or head. Two bushing adapters are included to change the 1/4"-20 thread to 3/8"-16 and vice versa. A hex key is included to tighten three built-in set screws to the tripod head.
