ZRFCXEWindow Locks,4 Pack Sliding Window Locks with Key for Vertical & Horizontal Sliding Windows Doors,Easv to Install,Adjustable Security Window Lock for Patio Bedroom Home and Office (Black)

Easy to use. Great peace of mind for my first floor. So far they have lasted well and had no issues. They haven’t come loose or fallen off.

The media could not be loaded. These work great! Fit perfectly and keeps the window from opening. Easy to install and looks great. We have the emergency exit window so I’m not worried about needing to get out. I’m more concerned with anyone trying to break into the trailer. I’m pretty confident that the window won’t be able to be opened from the outside. But if someone wanted to get in they cud just break the window, smh. They are metal and good quality. They are easy to remove with the tool but not without it. We were given multiple tools so we can place them several places so we will be able to find one if needed. We did leave one in the RV. I recommend these for anyone who wants to keep the window shut.

I bought these for my daughter to help her feel more secure in her new apartment. They seem very sturdy and grab on to the window rails firmly. They were easy for her to install herself.

Cost effective, easy to install and does what it needs to do. Extra keys are provided for added convenience and safety. Only downside would be a lack of a quick release in case of an emergency. This could prove detrimental if this product was blocking your only egress.

Works great. Easy to set up. Great price. Fits nicely and adds to safety.

My partner said this product is very good. It was easy to assemble and we have not had any issues. It's very sturdy and reasonably priced. This was to keep my AC in place and to deter anyone trying to push the AC in. We will use it for the winter months.

Simple, easy to install and works great! I learned when I had to get in my house how easy it was to break it when I climbed to the second floor and just slid the window open. Installed these and they work as intended

When I received them the first thing that I noticed is they are a little shorter than ones that I had bought in previous. However they still felt very heavy duty and seem to work really well they get really tight on the window frame they are easy to install and each one of them comes with its own key plus one extra. So that's nice. They fit well and stay in place on all of my windows. They function exactly the way they said they should. So far no issues. Removing them is just as easy as putting them on You just need to use the key to take them off. so far from what I can tell for the cost not a bad product.
