Chain Lock Oxford Big Boss Alarm 150 cm

The Chain Lock Oxford Big Boss Alarm is Oxford’s strongest ever lock with an integral alarm. It boasts a 12mm square link chain, a padlock that has a 16mm shackle and an ear-splittingly loud 100bB alarm which is triggered by movement sensors (the padlock can also be engaged without setting the alarm). The alarm unit is removable and sealed (waterproof).

The shackle can be used as a disc lock or a padlock. Both the chain and the shackle have been tested against drills or bolt croppers – the anti-jack design of the padlock can withstand up to 4.5 tons of tensile load. The cloth sleeve protects not only the motorcycle’s paintwork but also the lock from dust and mechanical damage. Last but not least, the lock comes with 3 (replaceable) keys.
