Master Lock 496B Lockout Tagout Universal Wall Switch Cover, Red 0.312 in. Shackle Diameter

When I converted my 3rd car garage into a workshop, I wanted to prevent accidental opening of the ovehead door. This serves that purpose perfectly.

My old lady woke up one morning in an absolute panic. It was cold. The furnace was off, no lights, no nothing. While she began running around in circles muttering incomprehensible gibberish, I took a sleepy eyed walk down to the basement. I couldn't figure out what was going on, so I called a repair guy. Repair guy gave me a time estimate between late afternoon and eternity. Fantastic. I logged into work, marked myself as work from home so I could be there if he ever decided to show up. Old lady was basically fetal at this point, but I got her out of the house and off to work. I eventually remembered we had two emergency power switches for our furnace. One on the furnace itself and one up the stairs. Sure enough the one on the stairs was off. I flipped the switch, waited a few minutes for some warmth and cancelled the repair guy. Old lady had apparently turned it off instead of the lights the night before. This switch cover was mandatory after that morning. It installs in 5 minutes, including time to grab a screwdriver. It'll work on the big rectangular decora switches, you have to snap out a couple plastic pieces first through. Works with the older, smaller blade style ones (what I have) without problems too right out of the box. Once installed it puts a quick flip up door over the switch. The door snaps shut. There's a spot for a lock, but I have no idea who that would actually keep out other than a toddler or something. I wouldn't call this a security device at all. No more accidentally turning the furnace off. Keeps old lady happy (and warm). No more crazy mornings because of a switch.

The cover keeps coming off when I need to turn on the switch. I have it to cover a toggle switch that turns on my garbage disposal. My dog accidentally turned it on jumping up near it. It is a little difficult to lift the cover and then it comes off but not too bad to put back on. Better than having the pup start the disposal with my hand in there to retrieve something. I have no desire to be called Lefty for the rest of my life.

This is good for anybody that needs a light switch, not turned off all the time.Good product were recommended to anyone.That needs a lock on a light switch

As expected, this works like it should. We use it on our furnace power switch. We have an old furnace and the power switch is on the side of the furnace. Unfortunately, it is in the path of where we walk when going to our washing machine. So, we have a bad habit of rubbing it accidentally and turning the furnace off. This means, until we notice, we either don't have heat during the wintertime or a/c during the summer. I bought this, put it over the switch, and we no longer worry about that problem. The cover can work with both regular light switches and with decora style switches. Very easy to install - just unscrew the existing faceplate screws of your switch, place this over the faceplate and align it over the screw holes and replace the screws. If it turns out the screws you originally had are too short, this cover conveniently comes with two long screws you can use instead. Brilliant! The only wish I had is that this comes in other colors other than red so that if you wish to use it in the house (such as in a baby's room) it doesn't stick out like a sore thumb and can match your wall color/decor.

I have a toddler who loves to flip lightswitches. I have one switch for an outside light I NEVER want switched, but he hasn't quite figured that out no matter how logically I explain it. This red cover is really meant for lock out-tag out safety use, as you might find in any large factory with a professional maintenance staff. I find that quite amusing! Its fine for home use. You don't even have to put the "Danger" sticker on it if you prefer not, but again, I found it subtly humorous to do so. The box itself does a fine job keeping out toddlers even without a lock. It is a bit difficult to open -- not hard for adults once you know where to grasp and pull. But toddlers won't figure it out. If you like, you could even slide a paperclip or padlock through the hole to keep it confidently shut. It was surprisingly impossible to find any other item like this in any local store, or even on Amazon. (A lot of the other ones on Amazon seemed too expensive for what you got, or too flimsy, or really not able to keep a child out. This does the job.

I have a toddler who refuses to go to sleep if the light is on. When I leave the room, he immediately turns the light on. We remedied this by unscrewing the light bulb for a while, but this was a less than ideal solution, especially after dark. Now, I realize this thing wasn't likely built with toddlers in mind. It worked perfectly to keep access to the light switch out of his hands for a few weeks, but because the plastic is kind of cheap and it's only held on with the two switch plate screws, it was easily broken. I'm actually sad because this design was just what I needed. I just need something a little more sturdy.

Excellent idea!

Got this because one of my co-workers like to turn off the lights on his night shifts & go to sleep so this wonderful product is changing it, works so good got 4 more

Parfait pour sécuriser une entrée électrique, peut être un bémol sur la qualité du matériau employé : à voir à la longue.

It was cheap and lived up to suspicions. It arrived poorly packed and broken but for the price not worth bothering with a return. Lesson learnt, quality pays for itself...

Era lo que buscaba para proteger mi pastilla de luz. es seguro y facil de poner. Es para uso casero, pues si buscas alta seguridad no es el mas indicado, ya que su material es de plástico. Para mi fue perfecto!

I purchased this item to deter my husband (who has Alzheimer's) from switching off our furnace accidently. He wasn't able to distinguish this switch from a light switch. It was easy to install on my own and he hasn't bothered it since. :) I would recommend this product for anyone that needs to keep specific switches under lock and key, out of curious reach for safety reason.
