Circuit Breaker Lockout Device, 4 Pack 480/600 Volt Clamp-on Single Pole Breaker Lock Out Device, Large

Only works for big leg breakers like 2 poles, 3 poles, or singles for more than 30 amps.

Perfect

They don't work on all breakers. They will fall off once you up a lock on them at times.

Product arrived on time and well packaged. They install easily and work as intended. These are of course designed for single breakers. They CAN fit some double breakers depending on the layout of your box and the type of breakers used.

Not super tight fit, but works. Easy to attach.

I have been waiting to write this review because I wanted to find a circuit breaker that these worked well with, I have not been successful. I have put these onany different brands of circuit breakers and they seem the same on every one.I don't feel safe putting these on a breaker, locking it, and walking away, maybe if I was the only person on site, but only maybe.While I have not turned back on a breaker with this attached, it felt very close and if I pushed harder, I think it would turn back on and/or breaking the lock-out in the process. I have not found a brand of circuit breakers that feel better, every brand I've tried has felt the same, like I could push a little harder and turn the breaker on.Maybe if these were a bit longer, to cover more of the breaker, than maybe they would feel better like they would keep the breaker off.

Works but can't shut cabinet door

It takes a little while to know how to hook it up after that it works good
