BsBsBestSliding Door Security Bar Inside 2 Pack Adjustable 18 to 51 Inch Window Security Bar Interior Black Window Locks Security up and Down Window Bars Security Extendable

Good security upgrade to my porch door in my apartment. I like that you can tighten (extend) it with a wrench to very snuggly keep the door closed/secure.

When we moved into our apartment all we had is a little wooden stick to keep our sliding door secure. Got this for more security to have when the wooden sticks fails and our sliding door slides open. It is adjustable and you can figure out the size you need to make your doors secure. I didn't have difficulty putting it together,

This is simple to put together and I am pretty sure it will do the job from someone opening the window unless they break the window. I am 66 years young and I am happy with purchase and I bought another one for the other window.

Used to hang a large, heavy stained glass art object half way up a window. Easy installation and strong enough to hold the art piece.

Very well-made product and easy to use! I recently moved into an apartment w/ sliding glass door access to the balcony. There is a safety lock on the door's handle, but the BS Adjustable Window Security Bar provides an extra level of protection from breakings! The product is sturdy once assembled & very easy to place in door track to inhibit movement. I chose the black color because its easily seen & hopefully a deterrent too! At $19, this is a steal....no pun intended😁✌️!!! I also plan to get one more for the window in my bedroom!

Easy to assemble and works great!

This window security bar is exactly what I was looking for! It’s sturdy, well-built, and provides great peace of mind for extra home security. The adjustable length makes it super versatile—I was able to fit it perfectly on both my windows and sliding door.Installation was a breeze—just extend it to the right length and lock it in place. No tools or drilling required! The black finish looks sleek and blends well with my home decor, and the bar itself feels solid and durable.

We have this at our back slider and it helps me feel extra secure. It does the job well.
