Modern triangle locks use a precision-cast triangular lock body, which has stronger resistance to prying and shearing than ordinary locks. It can maintain structural integrity in the face of external damage and effectively resist illegal intrusion. The triangle lock has a built-in high-precision lock cylinder and adopts the latest anti-drilling, anti-prying, and anti-opening technology design to ensure that only legal keys can open it; the triangle lock shell is made of high-quality stainless steel or zinc alloy material, which is corrosion-resistant and anti-oxidation.
