First For Performance

This breaker lockout works well with many circuit breaker arms where there is no hole in the breaker arm. The "no tool" design uses a thumbwheel to tighten the clamp onto the breaker arm. A padlock, hasp or cable lockout is then placed through the closed cover to keep the device safely in place.

This model works on switches up to a width of 41.2mm (1/12")

Clamp-on breaker lockouts are versatile and easy-to-install using the proprietary thumbwheel design - no screwdriver needed!
Extremely versatile. This works on a wide-range of single-pole and internal-trip devices. Detachable cleat expands the range of applicable breakers.
