The Magnum is an extremely strong U-lock. It features a high-security lock, with an independently approved 16mm shackle and hardened steel construction, and has undergone rigorous testing, achieving Sold Secure GOLD, ART 4*, SBSC, and FG certification.

The Magnum comes with a key replacement service. When you purchase your Magnum, simply note the number attached to the keys on a metal tag. Keep it in a safe place, and then, in the unfortunate event that you lose all your keys, it will be possible to have a new key made for you.
