Mastiff series chains & locks are packed with features, and provide superior security for medium/high crime areas.
The premium Mastiff lock has our special X4P locking mechanism and Z-Cylinder for high security, and a big 5.5 cm X 5.5cm shackle that can even be used as a disc lock. Our chain has 10mm hexagonal links for high security, and the special “sinch loop” design offers even more versatility.
