All SIRUI TY Series Quick Release Plates are made from forged aluminum alloy. The forging technique produces high-density metals with much greater strength than die-cast methods.
Standard TY and VH Series QR plates are designed with slide-stopping rubber mats to prevent the camera/lens from moving while tightening the screw. All plates are Arca-compatible.
TY-70X are standard on Ballhead K-40X
