Some say that size doesn't matter. When it comes to locks, it matters! The Oxford BEAST is so big it comes with a health warning on the box: WARNING - HEAVY! The lock alone weighs 3.6kg, and the chain 12kg - 15.5kg!

When you have a lock that is a Beast, you are going to need a chain that is also a Beast. The Beast chain would not look out of place attached to a ship's anchor. It is our largest and strongest chain, ever. The 22mm hardened steel chain links each weigh the same as a bag of sugar. The links are covered with a protective and reflective material sleeve.

The Beast lock, chain, and anchor have achieved a Sold Secure DIAMOND rating, ensuring it is able to withstand forceful and sustained attacks. To be awarded a DIAMOND is no small feat. The Beast has passed attack tests from a huge range of tools, commonly used by thieves including, pliers, bolt croppers, drills, and most impressively a 90-second angle grinder attack.

International security standards agency ART, has awarded the Beast a 5-star rating. ART produces a 1-5 rating (5 being the strongest) based on a whole variety of tests performed by both machines (tensile strength, torsion strength, cutting, corrosion, dust, and freeze tests) and by test engineers (brute and intelligent attack tests).
