Manfrotto's RC4 L Bracket provides a quick, easy, and precise way to change your camera position from a horizontal to vertical orientation. The lightweight magnesium alloy bracket features anti-rotational systems that provide a snug fit on the camera body, to guarantee stability even with heavy-duty professional equipment. The bracket keeps the weight centered over the tripod, avoiding lens movement when changing position. Two 410PL type quick release plates are built into the bracket for use with RC4 quick releases. The large area of contact with the camera provides a quick and stable lock for heavy equipment.
