The Vanguard QS-50 Quick Release Plate for PH-22 and PH-12 Pan Head is a camera plate that fits the quick release mechanism of the PH-12 and PH-22 pan heads. The plate’s 1/4″-20 screw connects to any standard camera tripod mount, and the video fixing pin keeps your camcorder from twisting, or retracts if there’s no corresponding hole.
The QS-50 can serve as a replacement plate, or as an additional plate if you use more than one camera on your head and would like to exchange them quickly.
