The TY-50 Quick Release Plate from Sirui is an Arca-type compatible dovetail plate with a 1/4"-20 male threaded camera mount. The aluminum plate features red pop-up anti-twist stoppers, which can sit against a camera or a lens tripod foot. The anti-slip pads combined with the stoppers can prevent any type of twisting or slipping between the plate and the camera. In addition, the safety lock design on the bottom of the plate prevents the plate from slipping out of a clamp if it is partially opened by accident.
