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.

Wanted something to secure the sliding glass door from the house to our screened-in patio (lanai), so we could leave it open "just a crack" for the cat to use. When fully extended in the track of our older sliding door, it leaves about a 6 inch opening ... perfect for our Fat Cat, but too narrow for a human. This ended up being considerably cheaper (and much easier) than installing a cat door! There is virtually no installation. We just set it in the track, and even my adult son can't force the door open when it's in there. For added security it can be attached to the wall ... which I haven't gotten around to yet, but looks very easy to do.

Works very well

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

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.
