The Alta BH-100 Aluminum Alloy Ball Head is compatible with tripods and other support systems that have a 3/8"-16 mount. This ball head can support a maximum payload of 22 lbs and rotates at a 360° angle with the assistance of its independent lock. This Arca-type ball head comes with a reducer bushing that helps in teaming it with tripods and support systems that have a 1/4"-20 mount. For added flexibility, the ball head tilts up and down at an angle of 90°. The bubble levels along the integrated clamp’s edges help in capturing landscape and portrait shots. Moreover, the retaining pin on the clamp prevents the quick-release plate from sliding off when the clamp is opened. The aluminum-alloy construction of this ball head makes it lightweight and sturdy.
