The 3157ANR plate features a 3/8" camera screw, and offers a solution to the problem of unwanted movement between gear and quick release plate. This plate, which works with all 3157-accepting Bogen quick release assemblies (RC2), features a metal lip which can be positioned in front or in back of the camera/tripod collar to eliminate rotation.
