Best for small breakers
Simple to use and reliable. Turn to knob until the pads touch both sides of the breaker, close the cover and it clamps down. Simply, easy, reliable.

Good piece of safety equipment.
Works with all single, double and triple pole standard breakers. Adjustable finger screw allows for a snug fit on all types and brands.

A little sketchy installing but ultimately served its purpose.

Is 30-seconds of work worth it to save your life?
I was very pleased this was adjustable enough to fit this breaker handle. Was a 480Vac 3ph panel board. I found it fits a variety of BKRs from ABB, Siemens, Eaton, Sqr-D, LS-Electric & others. Don’t panic if the angle of the grippers doesn’t perfectly align with the angle pitch of your breaker handle, just tighten it down, lock it, & you’re good to go. I trust it on the job. Great value, easy to use, it’s worth 30-seconds to keep me alive.

Lock out
This is a very secure breaker lockout. However, this will only work on breakers in a single row, not if there are breakers on the opposite side. When the opposing breaker is in the on position, this device hits the opposing breakers handle wanting to turn the breaker off. To bad it’s not designed to be mounted with the lock facing to the right instead of the left.

Great product but it didn’t fit on MY panel
Looks like a great product but unfortunately for me it didn’t work I had no space on the panel in order to fit :/
