OnGuard Mastiff Loop Chain with X4 Padlock 110cm x 10mm

Product Code: 140796

With slightly smaller, squared links compared to the BEAST chains, the MASTIFF series offers bicycle owners and powersport enthusiasts ultimate security for use in high crime areas. Oversized, titanium reinforced hexagonal links render hacksaws and bolt cutters virtually useless while tight inside link dimensions make prying impossible. Available in a wide variety of chain lengths and link sizes to match your security needs. 

OnGuard's Mastiff Chain is the lock you need to protect your bike in high-risk areas. Its 10mm links resist attacks from saws and cutters, while the X4 padlock resists picking, drilling, pulling and bumping. This lock comes with 5 keys, including one with a built-in light.
