DEROFIT Window Security Bar 2Pack, 16 to 51Inch Adjustable Sliding Door Lock Bar- Dual Use-Patio Sliding Door Security Bar or Window Security Lock, Child Proof Window Security Bars Window Stopper

good product

Nos sirvio mucho para una ventana, muy buena calidad

A MUST HAVE!!!!! The instant feeling of security I had as soon as I installed it is unexplainable👍 This security bar is very sturdy and was a breeze to install. Do yourself a favor if you don’t have one, run don’t walk to purchase🙌

These window security bars work exactly as promised. Once installed, no one can slide the windows open from the outside — the only way would be breaking the glass. They fit perfectly and feel very sturdy. The adjustable length makes them easy to place on different windows, and they stay firmly in position without slipping. They give us a lot more peace of mind, especially at night.

Nice, solid, easy to adjust.

Good product and very customizable for all window lengths. I am on the first floor at my apartment building so this is great for extra protection.
