OnGuard Mastiff L Chain Lock

The Mastiff L Chain Lock, made by OnGuard, is a longer 180x10mm titanium reinforced, hardened steel hexagonal link chain that offers more locking options. You can also use the Boxer U-lock alone as a disc lock. The chain dimensions are 180x10mm. The lock features a bump-proof and pick-resistant Z-Cylinder, and its rounded design and centred keyway eliminate pry points. The co-moulded crossbar cover and double rubber coated shackle protect your finishes, while the all-metal end caps provide additional protection against hits and drops. The lock has automatic keyway covers that help seal the internals against the elements. The 10mm titanium reinforced, hardened steel hexagonal link chain is resistant to cutting or prying, and the chain cover protects your paint and finishes. The embroidered logo on the lock won't flake or wear off. The Boxer U-lock can also be used as a disc lock. The Mastiff L Chain Lock features an X4P Quattro Bolt locking mechanism and a Z-Cylinder tumbler mechanism. The shackle diameter is 14mm hardened steel, and the keyway is automatic weather resistant. The lock comes with 5 laser cut keys, one of which has an LED micro-light. It has a lifetime warranty and includes an embroidered chain cover as an extra.
