OMOTOOL Child Window Restrictor Casement Security Lock (2 Pack) Kids Prevent Children Falling Window Lock Baby Protection

Perfect

Needed something to prevent the window opening enough for the cat to get out. The holes aligned perfectly with a similar device that was installed in 1930. I like the fact this has a key to unlatch the cord if you need to open the window. I wish the cord was adjustable in length after installation, but that probably would add to the cost and ease of production. Just make sure to install it as desired the first time. I don't think this could stop a burglar.

Easy to install and does the job.Considering the price tag for a package of two and what the product does in ensuring my child’s safety, and these are a steal. I use them on windows because my autistic child sometimes elopes and has no fear of going out windows even on the second or third floor. They also are useful for closet/cabinet doors I need to keep him out of. Technically, these could be a fire hazard because the windows can only open a crack but it’s nice to know the key for the lock is all the same so I just keep it on me at all times.

Actually a great buy. Might buy more to be honest. Only problem we'll not problem but more of a disappointment is all keys unlock all locks. So if one is stolen all can be unlocked. But is one is missing them you can still unlock all of them.

My son (age 5) is that kid who is always trying to escape -- and who can figure out any window latch, doorknob cover, cabinet lock that we have ever tried. And if he can't, he just breaks them. You can see one failed culprit in the photos. We are building a porch and the roof is right outside his windows, and I know the temptation to climb out there will be way too much for him. So, we needed to find something. After much searching, I came across these and decided to give them a try. Installation took me all of 10-15 minutes for 3 of them. The windows in question are vinyl, double-hung windows and these things are perfect as long as you install them in the right spot. I had to adjust placement a little to make sure the window didn't open too far, but once I got that figured out it was a breeze. They are inexpensive, strong, and relatively unobtrusive -- and now my husband and I can sleep knowing our son can't climb out his windows! Fantastic product!

These work! I wish I knew about them earlier, before buying and modifying expensive rails that ultimately do not fit or work in windows that open vertically. I highly recommend these restrictors for vertical windows.

Had to turn my house into Fort Knox to keep my son from escaping. I didn't want to put holes in my window frames, but the other designs on the market were only baby-proof instead of kid-proof.Install was cake once I figured out which way to orient the pieces. The self-tapping screws were -chef's kiss- and saved me time pre-drilling. You can put the locking end in other side so you can make the key turning direction the same on each window.No complaints, here. Construction seems very solid.

These locks attached very well to my vinyl window frame and wood panel. I used a small drill bit to create guide holes for the screws. I think that helped a lot, especially for the vinyl windows.If you are looking for window locks that will still allow the window to open a few inches these are a great choice.
