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!

Cette barre empêche la porte de la véranda de s'ouvrir de l'extérieur. C'est une sécurité car souvent les serrures de véranda ne sont pas terribles

Macht genau das was es soll. Qualitativ hochwertig. Passt in einen normal großen Koffer, falls man es im Hotel benutzen möchte. Von mir eine klare Empfehlung.

love this. I feel so much safer with this on my patio door then just the little handle lock.

Solid, easy to use, far superior the the dowel we were using!

Concerned about security for your sliding patio door, then this item I highly recommend. Very good value, easy to adjust ie from allowing a 4inch ventilation but keeping children and dog inside, to extending to prevent the sliding door being opened at all. Peace of mind when one is away from the property and at night.Have tried opening my door forcibly when the lock is in place, no movement at all. Have already bought a second one for newly installed sliding door.
