Sliding Door Security Bar,2Pcs 16 to 51 Inch Inside Sliding Patio Door Window Security Bar Stopper, Adjustable Window Locks Security Bars for Home Apartment Security, Sliding Glass Door Lock Hardware

Very easy to assemble and install. Took me less than ten minutes for two windows. The security bars fit nicely to the sides of the windows, so they’re hidden from view. Bought another set and will buy more for all my windows in the near future. Overall, these are an affordable and convenient layer of home security.

A great safety purchase. I live downstairs and a large window faces close to the street. I need fresh air and this fits the bill. Very sturdy and easy to adjust length. One is used for a window and one for a sliding door in my bedroom. Feel very safe while sleeping.

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.

I live in a rental with faulty windows that will slide down from the top and I use these to keep them secured and closed. They're easy to assemble and work pretty well for that purpose. I bought one initially, and then came back to get a couple more for other windows in the house. Very straightforward to use and does the task it needs to do.

I put this on my office window about half way up. It was a bit problematic to get it juuuust right so it didn't slide down. But with some effort it I got it to stay where I wanted it. So far it hasn't moved and is holding strong. It's great that you can adjust it to fit your window, exactly. Very happy with it and would recommend.

The item is fantastic! Easy to use and is adjustable.

My old windows don't have the most reliable latches, especially when the wood swells in summer. Love these and they are hidden to the side so not unsightly like burglar bars. VERY sturdy and easy to install. Would definitely recommend.

This is great addition to my home security. It’s easy to remove and place in an additional area as well. It’s very study and works well. I have purchased two.

Nos sirvio mucho para una ventana, muy buena calidad

good product

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.

I used it for windows that open upwards in an area that faces an alley. It was easy to put together and maneuver into place. They seem really solid and strong. Worth it for a bit more security,

Tardo en llegar mucho más tiempo del sugerido, no pude cancelar el pedido, pero ya que llego son bastante fuertes, de buena calidad y fácil de usar
