The Monster XL ultra-strong padlock is the same padlock that comes with the Oxford Monster XL chain lock.
It features boron steel armour casing and 16mm shackle with double locking mechanism.
It comes with three keys. On receipt of the padlock take a note of the key number and keep this in a safe place. If you are unfortunate enough to lose all of your keys a spare key can be made up for you using this number.
