The Sachtler Sandwich Touch and Go Adapter with Touch & Go Plate 16 allows retrofitting other heads or equipment with the Touch & Go quick-release system that is compatible with Sachtler's DV12, Video 15, 18, 20 and 25. By adapting other equipment, such as a tripod head, monopod or a crane, to use this QR plate you don't have to change the plate on the camera when switching between heads. The adapter attaches to heads or other support equipment using available 3/8" screws. The QR system features a safety catch to help prevent accidental release of the plate. The included Touch and Go Plate 16 features one 1/4"-20 & one 3/8"-16 captive camera tie-down screws.
