You can buy a set (Alta Pro 263AT Foot + Ball Head SBH-100). The advantage of this ball joint with respect to the SBH-100: - It can support 30 kg instead of 10 kg. - Blocking the ball is provided by 2 comfortable knobs (coarse and fine) - The quick release plate can slide and be extracted from his hoof on one side or the other (but beware, it's not like a micrometer slide on a sliding tray macro)
