Mastiff
Mastiff series chain locks provide superior protection for medium/high crime areas and are packed with features
Chains made of titanium-reinforced, hardened steel links that resist cutting or prying
Chain cover protects paint and finishes, with an embroidered logo that won’t flake or wear off
Locking mechanisms secure the lock at multiple points: X4P Quattro Bolt shackles on models with separate shackle; X2P Double Bolt on models with integrated locking heads.
Locks use Z-cylinder tumbler mechanism that is bump-proof and resists picking, pulling, or drilling
Co-molded crossbar cover protects finishes and all-metal endcaps provide protection against hits and drops
Automatic keyway cover helps seal lock internals against the elements
5 laser-cut keys, 1 with micro-LED
