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. Review: Works as expected - can be used for regular and decora light switches - 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. ## Features - Best used for electrical lockout applications as part of a comprehensive OSHA compliant lockout tagout safety program - Lockout device hinges open for unobstructed normal operations of switch - Patented design assures switch stays locked on or off - Locks out both toggle and paddle wall switches with a padlock (sold separately) to help protect against switch operation during maintenance and repair - Dimensions: 4-3/4 in. (121 mm) L x 1-3/4 in. (44 mm) W x 1 in. (25 mm) D; Accepts padlock shackle up to 5/16 in.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ No more waking up freezing with panicked old lady *by J***F on April 16, 2015* My old lady woke up one morning in an absolute panic.

I have a two gang rocker switch in the garage. One switch controls the inside garage lights, the other a outside infrared security light that comes on at night. The security light circuit needs to be 'on' all the time and this lockout meets the need to prevent accidental shut off. The unit is not real sturdy so you need to be gentle when handling. I took a small thin blade screwdriver to open the unit and put a couple drops of oil on the hinge and worked it back and forth so it would open/close easier. The garage switch is a rocker switch - not the toggle type. The two screws that come with it are mounted in removable pieces that need to be removed when using this in a rocker switch application. Use a thin blade screwdriver to remove the two inserts that have the screws attached. The two screws repalce the switch faceplate screws that need to come off the faceplate when mounting this unit. If you are careful enough, this should work well for you. ## Frequently Bought Together - Master Lock 496B Lockout Tagout Universal Wall Switch Cover, Red 0.312 in.
