6 Pack for Sliding Door Locks for Sliding Glass Doors & Windows, Child Proof

We just bought our first home. We wanted a little bit more protection when we are away or asleep. We have a few windows that are close to the ground and deemed it's easily accessible if they were unlocked. If we fail to lock the windows or the lock fails, this would prevent from accessing the house and can cause quite the noise if you try to lift it open. You will have to manually flip these up to be used. When applying keep them closer to the middle of the window, because if you give the trespasser more room to ram it up, it can break off. These will come in handy when we have children. Having these out of arms reach will prevent them from falling out a window.

I searched for quite awhile before I found these safety locks. I have a two story home with sash windows and I needed safety locks which would allow the window to be open only 4 inches to satisfy safety codes. These are simple to install and and simple to disengage so that the window can also be opened fully when young children are not present. They also work on sliding glass doors. They are sturdy and clear. You will not notice them obscuring your view if placed to the far left or right.

So far so good. Easy to install and seems like it withstand someone trying to pry a sliding door or window. at this point, I am installing in all my windows in the house.

I have used these previously on apartment windows. They are simple to use and worked well preventing the window from opening when hinged. However, I purchased them again for a new place with aluminum windows, but the area between each pane of glass was so close together, if applied, the window would not open at all even when flat and unhinged. So unfortunately, they did not work on the specific type of window we had. They would work well on sliding glass doors or larger framed windows. I returned them unused and without hassle.

This is the second set we owned (two different locations.) Never had an issue with them falling off. We used to have a set on our sliding door before upgrading, and even with slamming into the BurglaBar when opening the door, it never budged. We had one at the top of the door and one at the bottom; the slider faced the afternoon sun. We cleaned the glass with a glass cleaner for dust, then before we put the BurglaBar on we wiped the area with alcohol and set the bar. I have not had much luck taking them off -- but then we've never needed to.

I am very happy with this purchase. I have 6 of these up on various windows and a sliding glass door, and they are very strong and give me some feeling of security. I have not had trouble with any falling off - I cleaned the glass well with rubbing alcohol first and pressed fairly hard on them until I could not see any air bubbles in the clear adhesive. I have jammed these fairly hard with the sliding glass door, and they do not budge! When I purchased these, I was debating between getting them or those magnetic alarms that go off if the window or door is opened - I am so glad I bought these instead; I would rather deter an intruder from opening the doors and windows rather than just hearing the they are coming through the window! I also think these are great for baby proofing - my son went through a stage where he was trying to open doors and windows on his own, and these can easily be placed high above a child's reach ensuring their safety.

Adhesion seems to be hit and miss. I just bought the industrial grade 3M double stick tape and reattached them. Much much stronger, only downside is the new tape is gray and not transparent. Small price to pay for ventilation locks on double hung windows.

Thao is honestly a bit of a give in their direction. i think the idea is good; but adhesion is definitely not enough to prevent anything. It may make a person think twice but stop? It will not. They’re easy to install, but as advised... you can not but them directly in where the window opens... the space you must give for fire/smoke safety is actually enough that with any momentum at all the device will be knocked off. Good idea. Not quite there yet on design.
