Master Lock Electrical Device 493B Grip Tight Circuit Breaker Lockout, Red & Black, 11.3 cm x 6.9 cm x 2.5 cm

Me parece de buena calidad y robusto. un poco caro pero contento con la compra

Good breaker lock like the snug fit

I bought this breaker lock-out as a reminder to not turn this breaker on, unless you really need it. I use this on the 240V, 50 AMP, Electric Vehicle / Recreational Vehicle outlet that I installed under our breaker panel. Most of the time, this should be turned OFF, but on rare occassion it needs to be turned on. This Lock-out makes it really easy to remember to keep it turned Off when not needed and prevents people from turning it on by accident. The quality of construction is excellent and although I didn't need to use the fitment accessories that came with it, I appreciate that they were included. Nothing is as frustrating as not being able to finish a project beause of a fitment issue. Master Lock had this in mind and they have you covered. Great little product. I would definately buy it again.

Required to lock off mob isolator. Better designed mcb with locking capability would be better

Works extremely well . Was impressed . Would buy it again .
