This breaker switch lockout locks out circuit breakers, safely preventing unintentional energization of electric circuits. This model is designed to fit most major brand single pole breakers that have a recess hole in the toggle. Versions are also available for multi-pole breakers (item # 07045) as well as single breakers that lack a recess hole (item # 07046).
These patented devices are made from tough polycarbonate and permit access to other breakers. Padlocks are sold separately. The use of lockout tags is also recommended.
