BeBecome Sliding Door Security Bar，17-50 inch Adjustable Patio Door Security bar with Rubber Tips Apartment Bedroom Bottom of Door Heavy Duty Interior White

This sliding door security bar has been convenient, especially for my specific setup. I've got a portable window AC unit in my office, and the vent goes right out the window. My old screw-in window lock was a pain to deal with every time I wanted to open the window at night for some fresh air – constantly unscrewing it with a special key was just too much hassle.I ordered this security bar as a quicker, easier way to keep things secure without having to remove the AC vent or struggle with my old lock. And honestly, it's been doing the job perfectly. It fits right into the gap, creating a solid barrier to keep the window from being opened by anyone outside. But the best part is how easily I can remove it when I want to open the window, and then place it right back in when I need to.I also really appreciate that it's adjustable. That means if I ever need to move it to a different window or sliding door, it'll still fit. This bar offers peace of mind and amazing convenience.

This sliding door lock gives me so much peace of mind. It’s adjustable, easy to use, and the silicone stopper is sturdy and well-made. I feel much safer having it installed. Simple, effective, and totally worth it!

Works very well. Slides in easily. Sets up quickly and feels very secure. Very nice quality. Great fit. Excellent over all value! Definitely will buy more.

This is the perfect solution for securing a slufing glass door. Super easy to assemble, convenient to use with lots of room for adjusting width, and well built. A+

I bought this sliding door security bar after a recent break-in scare in our neighborhood, and I couldn't be happier with the purchase. It’s a simple, effective, and inexpensive way to add an extra layer of security to our home. The adjustable length is a great feature — it fits both our patio and basement sliding doors. It's also easy to remove if needed, like when we’re expecting guests or need to open the door fully.

Pretty sturdy and easy to assemble.

Very effective sliding door security bar. It’s easy to put together, and it has three different extensions so it’s easy to adjust to different lengths for a secure fit. I’ve tested opening the door and it’s strong to prevent opening.

I have 2 small children and this protection is very useful in our house, excellent construction material, easy to use and I can lock the door so the children cannot get out, I recommend it to everyone
