The Magic Arm With Quick Release Plate is an extra arm to hold things in the studio. One lever locks three pivot points, and it comes with a quick release camera base plate with secondary safety lock. The saftey lock is based on the 200PL-14 system. Ideal for mounting a camera or a camcorder exactly at the angle you need it. Fits any 5/8 female sockets, works especially well with 035 Super Clamp.
