AceMining Sliding Door Security Bar,Heavy Duty Sliding Patio Door Lock Bar, 20-50inch Adjustable Multi-use Window Security Bars, Sliding Door Stopper,White,2Pack

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

Great sliding door security rod works well to keep unwanted guests or nefarious people out. Adjustable to fit in any size door opening.

Really good product, exactly as advertised and really easy to install

Felt sturdy and was easy to install, however it didn’t fit my door. I will say it felt worth the priced paid but cannot attest to how it works

This bar definitely does the job!! It is heavy duty and comes with an extender bar although we didn’t need it. Love the added security and it’s super easy to use!

it works on our 3 panei sliding glass door! its obvioy but works!!!

Very sturdy and heavy duty

Super easy to use. You can make adjustments in just seconds!

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.
