## Description

AceMining Door Security Bar, Patio Door Lock, 20-50 in | Sliding Glass Door Security Bar for Patio Door, Window Security and Door Stopper Protection, White - desertcart.com

Review: It works!!! - Easy to use and strong. Secures door so it won't open from outside the room. Safety excellence.
Review: Simple Extra Security for Doors and Sliding Glass Doors - I picked this up for additional peace of mind, and it does exactly what it’s supposed to do. Setup was quick and didn’t require any permanent modifications, which makes it great for apartments or rental properties. Once adjusted to the correct length, it feels sturdy and stays in place well. I especially like that it can be used on both standard doors and sliding glass doors. The rubberized ends provide good grip without damaging the floor, and it stores easily when not in use. No security device is a substitute for a good lock, but this adds another layer of protection and makes me feel more comfortable when I’m home or away for extended periods. For the price, it’s a simple and effective security upgrade.
