Master Lock S3822 Grip Tight™ Plus Circuit Breaker Lockout Device

Master Lock S3822 Grip Tight™ Plus Circuit Breaker Lockout Device

The Master Lock S3822 Grip Tight™ Plus Circuit Breaker Lockout Device is designed for locking out moulded case circuit breakers (480/600V) during electrical maintenance and isolation procedures. Its lightweight, one-piece design installs quickly and consistently without tools, making it a practical choice for routine lockout/tagout work.

The device uses a stainless steel thumbscrew and curved blade to achieve a tight grip on the breaker handle, while a permanently fixed cleat adds physical blocking to help prevent the switch moving back to the “on” position. It is also designed to suit a wide variety of circuit breaker handle shapes and sizes.
