The Magnum OnGuard Mastiff 8019L is a Sold Secure approved and tested Bike padlock and chain, with a bump proof cylinder in the padlock.
OnGuard chain locks offer bicycle owners extra length for locking versatility plus the highest level of security for use in high crime areas. Massive, titanium reinforced hexagonal links render hacksaws and bolt cutters virtually useless while tight inside link dimensions make prying impossible.
