TURBRO Adjustable Window Security Lock Bar, Sliding Door Jammer, Extendable from 15.5" to 29" for Sliding Windows with AC Unit Installed, Stainless Steel

Very strong and sturdy. I use this for my window when i put an AC unit in it. Very secure.

Good product.

Just installed 4 of them and they are easy to install and seem sturdy. They could be a little more refined as in cleaning them (they smell like the oil from the machines that make them) and maybe add paint or powder coating but other than that they will do the job of stopping or at least slow the bad guy down enough to grab your gun and call 911.

Does what it should do. We have a cat door in our window so this was an easy fix to feel safe.

Didnt fit my window. Not even taking it apart as it describes in the listing. I bought 2 of these to protect my kids windows.....what a waste.

In concept, this is great, but the reality is this product is very poorly made. If you want something that is going to give you piece of mind, this is not it. I bought it to install in a vertical sliding window, and it doesn’t do its job. If I were to put it in the window (which is impossible with the sticky Velcro they included) and giggle the window up and down a few times, the triangular pin that holds it in place would slip back inside, allowing the window to be opened all the way. Not well made at all. SorryUpdate** The product didn’t work for my needs, but the customer service was great! The seller was very accommodating and did all they could to make the situation better for me. I really appreciate that!

I have now bought two of these. They are perfect I have one in a window and one in a sliding glass door. They are easy to adjust and really solid!

Very easy to install behind my window, so my window will only open enough to get a good breeze of air through daily. It took less than 2 minutes to install after taking it out of the box. I was so happy with the product that I bought one for my patio door. I have tested both areas to see if I could break into my apartment and I am all good unless a stranger comes with a brick to break the glass.
