Review: No accidental overhead door openings - 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.
Review: No more waking up freezing with panicked old lady - 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.

## Questions & Answers

**Q: Video shows screws being removed from switch plate and then screwed back in off to the right. Do I have to make new holes in my switch plate???**
A: No new holes ! Simply screw on top is switch plate. Nice idea my son's father in law kept shutting the boiler off instead of the basement lights

**Q: Will this device fit over a standard wall outlet, preventing things from being plugged into the outlet?**
A: This is designed to fit over a rocker switch.
The mounting design for Deco-style and GFCI outlets is the same as a rocker switch.
It will fit over Deco and GFCI outlets to prevent things from being plugged in.
It will not fit over conventional duplex style outlets due to a different mounting design.

**Q: What is the size of the hole in the center of the cover?**
A: the open space inside the lock out cover is 1 1/2"H  x 1 3/8"w this will directly go over a standard toggle switch with cover, or a rocker switch with it's cover. if you remove the tabs inside you will have a open space of 3" H x 1 3/8" w, but when doing this the cover has to be mounted to the mounting screws of the switch. we will add additional pictures to our listing to help you

**Q: En la publicación dice paquete de 10, es así o solo viene una unidad?**
A: Si, viene en una unidad

### ⭐⭐⭐⭐ Could be better but not too bad
*by B***E on August 25, 2020*

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.
