Sirui B00K Aluminum Mini Ball Head 10KG/22.05lb Load (Black)

The black B-00 Series Mini Ball Head from Sirui is an Arca-type compatible, anodized aluminum head that weighs 7.2 oz and has a load capacity of 11 lb. The 2.76" tall ball head has a portrait notch on the side of the head that allows an attached camera to move in 90° angle, for vertical shooting. At the base, a scale with index direction marks enables you to accurately move a camera in a 360° pan and lock into place with its independent panning lock. The ball head also includes the TY-C10 quick release plate, which can slide out by opening the head's clamp, but a safety-lock release button needs to be pressed to release the plate as well.
