Jeacent Adjustable Window Security Bar, Patio Door Lock - Sturdy Steel, Extends from 15 1/2" to 29 1/2"

I’ve been using this adjustable window security bar for a while, and it really does its job. It’s sturdy and keeps your window from opening, so you feel safe and secure. The adjustable design works for different window sizes, which is super convenient. Overall, it’s a simple, reliable way to add a little extra peace of mind to your home.

Nice window lock! Works good.

This window lock bar feels sturdy and worked well in my small window to help secure my window AC unit. It was easy to install and gives some peace of mind. That said, it may not offer as much adjustability or range as some other options out there, so it’s best suited for smaller or more standard-sized windows. Overall, I’m happy with it for the price—it does what I needed it to do and feels solid enough for regular use.

I have an air conditioner in my front window so I cant latch it anymore. This gives me the peace of mind I needed.

This is extremely simple to use. I would probably buy another one or maybe several more if I ever needed them. One I’m using is keeping my window locked in Place. I would give it an extra star just for happenstance ask coincidentally the placement of the bar and the Place. I risk my head blocks. The sun perfectly in the morning. lol

Works very well

I used this to secure a vertical window that has a window AC installed. It's well made but I was actually close to returning it because it was just a little too short for my window. The next peg down was too tight and the next peg up was too short. Just then, I realize that you can unscrew the rubber portion at the bottom for micro adjustments. If you can't get a tight fit on your window, you'll want to use the screw near the rubber portion to get it as tight as possible. I do think the bar is probably better suited for sliding glass since it will sit flat on the sill and keep the window from being opened. For vertical windows, someone could just break your window and just push the bar out of the way. I still think it's good to have and extra peace of mind but I would probably go a step further with sash locks in addition to the security bar for extra protection. It will certainly defeat the average dumb crook but if someone really wants in, you'll want more than a bar that can be defeated by breaking the glass. It's still a good product and very well made and sturdy which is why I'm going 5 stars.

Not sure if I was using it on the wrong type of window but I’m sure it would work for some types. Did not work for me and isn’t super sturdy. I think it may only fit certain windows.

Easy to install and feels very solid. No issues. Happy with the purchase.

Bueno, funciona bien pero me hubiera gustado más largo

The best one. We used them for the basement window where our daughter sleeps very sound. And, for the new patio door and we just used the pressure without drilling a hole in the brand new aluminium which is not a good idea. My husband tried very hard to open the door and the window without even a slight move. Very happy with these bars.
