Super strong and adjustable

I purchased this to keep my toddler from getting out at night. I adjusted the length and placed it all the way up out of reach. It is very sturdy and easily adjustable. It's working and quiet the piece of mind. I don't even worry about this door opening anymore. It's exactly what I needed.

Great sliding window protection

Purchased 6 of these for my father-in-law's house. VERY easy to install and was so impressed I'm ordering another 3 so all his windows are protected.

works well

I use this when patio door is open. It won't allow someone to open it enough to come in. We keep it on one setting, because door also has a dead bolt, for when door is shut. But you could easily extend it so some one can't push door open at all. Only takes minutes to set in place.
