The SIRUI TY-70 is an aluminium Arca-type 70 x 39mm quick-release plate for SIRUI G20, K20x, and K30x heads, compatible with other Arca-style clamps. Its rubberised top surface grips the camera base, while two raised anti-twist pins physically resist shifting as the head moves. A flip-up tab on the 1/4”-20 mounting screw also lets you tighten the plate to the camera without a separate tool.
