The Aluminium Lock-Off Device is a slim, robust tool designed to securely lock off most domestic MCBs (Miniature Circuit Breakers) and RCBOs (Residual Current Breaker with Overcurrent). Made from durable aluminium, its compact size allows installation even in tight spaces where access is restricted by test buttons or nearby breakers.
This makes it an essential safety accessory for any professional electrician’s lock-off kit, helping ensure safe isolation during testing and maintenance.
