Adjustable Window Lock Bar, Shorter Window AC Security Bars for Child Safety, Window Stoppers for Small Vertical Sliding Windows/Dog Door, Extends from 9.8-16.7 in (Steel 1 Pcs)

This Adjustable Window Lock Bar allowed me to have peace of mind while I was away from home and at night. I used to put my air conditioner in the window on the first floor in the daytime and I took it out every night, and this was annoying and backbreaking for me. Once the air conditioner is placed in the window, the bar is very easy to set up but depending on your window, you may need to place something underneath the bar to fill the gap, this is due to the adjustable notches in the bar and your window may not line up to fit correctly. This is an easy fix with anything in your house, just be creative. I love it.

As Advertised. Works Great. Easy To Use. Just MAKE SURE It's Te Right Size For You. Measure Twice, Oder Once :-)

Unusable unfortunately I really wish it fit but it doesn’t it’s to small in either direction even fully extended

I see why this is made more for side sliding windows. I thought this would work for my up/down sliding windows and I could use it to keep my window partially open, but it does not work that way. I do think it works great for keeping the window completely closed and the only way someone could get it open would be breaking the glass. When used correctly it’s a really nice security feature.

works great, easy to use device

They were too short for my traditional windows, however the most disappointing part was it came with no adhesive 😳 so I don’t know what the dolls were referring to about adhesive cuz it didn’t come with them. Will be returning just because of the length tho.

Easy to use and put together.

Even fully extended do not fit my window. I don't have particularly large windows.
