Prime-Line Flip Action Door Lock, Reversible Privacy Lock, White, 2-3/4 in.

The house I moved into had these installed.. I had never seen them before, but I'm glad I learned about them because they are my favorite locks now. You can put them at any height, they are easy to install, you don't have to line up two pieces - this only screws into the door frame and not the door. At a glance they look like they'd be flimsy but they are incredibly sturdy and strong and add an extra layer of security to the door. It is relatively small, and lightweight, around 2" or so, and it's a good option if you are trying to deter kids since your can put it up high To unlock it you just slide it up a bit and fold it back and forth like a door. I'm not sure how well it would withstand someone kicking in a door, but I have added it to all of my doors for extra security.

We purchased this lock to keep our 4yr old from running outside whenever he wants to. The lock is sturdy enough that he cannot open the door at all and we were able to put it high enough on the door that even when he pulls up a chair to reach it...he does not succeed :-). The lock is flimsy enough for an adult to force open though, I wouldn't expect this lock to keep out an intruder that was intent on getting inside. Only negative about this lock is that the screws to install it are kind of cheap, the head stripped right away when installing. Definitely worth the few dollars it cost for peace of mind that our son will not sneak outside.

This is important my friend Dad has a problem eating at night and he wouldn’t listen to anybody and just lock changed the game now he goes to bed early. He’s more quiet and they’re saving money on food so this lock is exactly what they were looking for it’s not a normal lock and that’s what I wanted because he can’t. He can’t register it from a familiar lock. That’s why it works good

We got it to keep a child from escaping the house. It took about an hour to install because the screws are made of soft metal and immediately got stripped so the screwdriver could no longer grip them. After scouring the house for spare screws or approximately the same size we got it secured to the door. Finally, after the frustration of dealing with it for so much longer than should have been necessary, we turned the latch so it fell into the notch and tested opening the door. It opened right up! The notch is so shallow and rounded that the gentlest pressure against it from the door lifts the latch right out and it opens with virtually no resistance. What a piece of junk this is! Angry at ourselves for trying to save a few dollars when the security and safety of a child were on the line, we immediately ordered a higher quality door lock. Sure, it was about $10 more, but it installed within 5 minutes and most importantly, it prevents the door from opening! The peace of mind of knowing no young children will be escaping or opening the door for strangers is worth the extra cost. Avoid this cheap piece of junk! It's going in the garbage where it belongs.

Does what it advertises, but be aware the swinging part of the hinge that locks is not very deep. So if the gap between door frame and door is very large, the lock won't catch. Quality is good, though.

This device keeps my master bedroom door from being opened by my kids. I have a door knob lock, but they can pick the lock and open it! This device is not a security device, it only prevents someone from entering the room while you are still in it. Check your gap. When your door is closed and it is a tight fit...maybe less than 1/16" you may have to chisel some wood on your door jamb (frame) so that the device does NOT rub on your door when you close it. I traced around the shape of it and used a sharp chisel and slowly carved about 1/16" of wood out so that the device fit flush with the jamb. (My door is a very close fit with almost no gap at all). It was not difficult. I bought the white one to match my white trim and it definitely works. Make sure you are very very careful where you mount it. Do Not mount it for a tight fit on the door....if anything, leave 1/8" play so that the device latch can swing around and drop into place without you having to force it. Like I said, this only keeps your family out of the room that you are in...if someone leans in with force to push the door in, they can easily push the door in with their shoulder or by kicking it in. Excellent privacy device for a few bucks.

So I went the rounds on other products before I settled on this simple solution that ultimately was the only one that met our need. The goal was to keep our 3 year old in our house. We were able to use doorknob covers for 2 of our external doors, but our patio door has a handle-type opener and couldn't accommodate a knob cover. The door also couldn't be converted to a knob due to the custom opener / deadbolt system that was installed. Our problem was that the door is slightly offset from the wall and other products proved to be too bulky to allow the door to function after installation. I briefly gave up on finding a solution, but my son later escaped and had to be chased by my wife for several blocks before she was able to catch him. (The boy gives new meaning to the term "stinker") I went back to the drawing board and found this product. I was pretty skeptical, as all of the other products that I had tried were far more complex and much more expensive. I was very pleased to find that the product worked great and installation was a 2 minute process. Now my son is safely contained to terrorize my wife in the comfort of our home and we no longer have to worry about him carrying committing acts of terrorism to the neighborhood at large. It has been several months and he hasn't gotten out yet. (well in all honesty, he did get out once, but that involved a perfect storm of chairs and broom handles and luck, and tiny devious ninja skills. We confiscated the ninja tools (broom handle) and he was back to being foiled. House, thy name is Alcatraz. Thank you for making a product that is as simple as it is effective.

Lock flip is loose rather that tight.

The best, most reasonably priced solution we found for keeping our toddler safe. Easy to install. Easy to use. Simple but very effective.

Great quality and keeps our toddler from unlocking the front door!

So easy to use, very secure. It not only keeps our toddler from escaping but it's added security to our home. I'm ordering another one for our back door tonight!

Using it for babyproofing the house. Easy to install, small and discrete. Much more convenient than those big clunky handle guards. However, you do need to jiggle it a bit to flip it open. The mechanism is not very smoothe. Note: you can only use this on doors that swing towards you (ie. hallway closets, door to basement etc)

As I was not able to get this product from any store in my area, I ordered 2 at the end of October. Although very easy to install neither one of them worked properly from the get go. On both locks, the flip portion would not seat into the slots provided so they would actually lock. No matter what I tried they just would not work. It is very disappointing because they are compact, unobtrusive looking on the door and would be easy to use if they actually worked. However, I would not risk ordering them again.
