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, the chain 15.5KG!

To put this into context:

• The BEAST has a 30mm locking pin. Our next biggest is 16mm and that one is approved to the 4 highest international security standards!
• The BEAST lock body has a 90mm girth (the same as a pint glass) and all of it solid steel
• The 22mm hardened steel chain links each weigh the same as a bag of sugar

The Beast has a key replacement service. When you buy your Beast, simply note down the number which comes attached to the keys on a metal tag. Keep this in a safe place, then in the event that you are unfortunate enough to lose all your keys, it will be possible to get a new key made up for you.
