Product Description

Size: 1-Pack

The Master Lock universal wall switch lockout covers both toggle and rocker wall switches and combines with a padlock (sold separately) to help protect against switch operation during maintenance and repair. This lockout installs over the switch plate, using the existing screws. Once installed, the hinged cover can be left open when not in use to allow normal switch operation. The locking hole accommodates padlock shackles up to 1/4" (6 mm) outside diameter. This lockout is made from a red polycarbonate for visibility and impact resistance, and the cover is translucent to show whether the switch is on or off. The lockout ships with two "DANGER" labels, one Spanish and English, and one French and English. This device is part of a lockout/tagout (LOTO) safety procedure required at facilities where electrical switches need to be isolated during maintenance and repair.

Lockout/tagout (LOTO) safety procedures require that lockout devices meet Occupational Safety and Health Administration (OSHA) 1910.147(c)(5) standards for quality assurance. LOTO devices use color, warning labels or tags, and sometimes a physical barrier to help prevent machine operation or power activation during maintenance and repair.

Master Lock manufactures padlocks, combination locks, and related security products. The company, founded in 1921, is headquartered in Milwaukee, WI.

We purchased this item to place on a light switch in my 2 1/2 year olds bedroom. She was waking up at night, and turning on the light to play. Instead of using a padlock with a key to keep it closed, we use a metal key ring that is easier to open and close without having to keep track of a key. It has been a great purchase and would recommend to anyone trying to keep the light switch off!

It keeps people from turning off my automatic light wired to a photocell. Longer screws were included which came in handy. I wish it was a little more "decor" friendly, but it works. I may paint it another color.

The "LOCK OUT" sticker shown in the picture does not come pre-installed, so you have the option of adding it.

Item as described. A little difficult to open but I view that as a positive. Quality build and you can put the stickers on or not. So if you want it to stay solid red then you are set.

I have a son who thinks going to bed isn't as glorious as I think it is. We had already solved the problem of 100 visits back to bed with the door monkey (check it out, it's awesome), but the light was becoming the toddler parent frustration of the month. This little gadget worked perfectly. I have rocker switches with white decorative covers, so no screws were showing. All I had to do was snap out the decor cover to reveal the screws, take those out, and and the switch cover screwed in easily with the provided longer screws. Sure, the product is hideously bright red but in the world of parenting a spirited toddler, it is nothing. The cover snaps shut and he is isn't quite strong or dexterous enough to get it open, so no lock has been needed (and trust me this smart 2.5 year old had tried). It is an inexpensive and effective way to childproof a light switch. Highly recommend.

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.

Had a hell of a time trying to find a cover to toddler proof our light switches, they fit they are not perfect as our rocker switches are a bit large for it but they work well enough. Shame the colors are limited to red as they are a bit of an eyesore in the living room but we live with it until the girls are older and learn not to play with the switches and we are now no longer going batty trying to keep lights from constantly going on and off.
