The SIRUI TYuni Series quick release plates have a 1/4" standard thread for the camera and have rubberised surfaces to prevent accidental slipping. Plates are compatible with the Arca-Swiss system, for example with the SIRUI tripod heads.
The two red sliding stoppers can be erected to stabilise the camera or the lens for portrait shots or when tilting the head (not TY-C10, TY-50E, TY-BG, TY-LP75). The 1/4" screw has a handle to tighten the screws, so no tools for mounting is required (not TY-BG, TY-LP75).
