GYROBALL Adjustable Alarm Door Stopper: Anti-theft security device
This adjustable door stopper is perfect for renters who want extra security without damaging door frames. It gives you peace of mind when you're home alone or traveling.
Unlike basic door jammers, this device combines a sturdy brace with a loud alarm. The alarm triggers if someone tries to force the door open, alerting you immediately. It's detachable and non-slip, so you can easily move it between rooms or take it on trips.
Install it in seconds by adjusting the length to fit your door. The silver finish blends with most decor. Use it on bedroom doors for added personal protection or on entry doors as an anti-theft security device.
