This is very sturdy and easy to use. High quality and does the job well. Would buy it again.

Works great. Good sturdy bar.

Perfect fit, many sizes, easy assembly, adjustable and easy application! Pit bulls not included 😉 This was a good choice purchase after a spark driver dropped off groceries then started taking video and pictures and canvassing the house.

Worked well for me. I put one in my sliding glass door and another one in the window.

Security for sliding door. Work great keeps me safe an secure

Fits perfectly - adjusts to the size of the door. Exactly what I needed. Good value for the money and easy to install. Blends right in with the door which is great because I do not want it to be noticeable. Very durable.

Easily adjustable and to use. Very secure

Works great. Much easier on my back than using the old broomstick in the track!
