🚪High-sensitivity alarm system
This portable door stopper is an industrial door security system that prevents unwanted, forced entry. Thanks to the highly sensitive sensor, an alarm is triggered immediately with any vibration, ensuring your sleep is optimally protected. Also suitable for public buildings, schools, and offices – for everyone.

Improved door stopper
The improved door stopper is made of thick aluminum alloy, break-resistant and durable in use. The bottom is made of high-quality rubber for strong grip and abrasion resistance. Thanks to the clever design, the force is perfectly distributed, effectively blocking the door against break-in attempts. Feel safe and worry-free.

Easy installation
No tools required. Simply place the door stopper in the gap under an inward-opening door within seconds. Position the door stopper directly under the door handle and then adjust your foot so it firmly grips the floor. In an emergency, you can quickly remove the lock by pulling it upwards. Note: Test before use to ensure the door stopper is stable.

Small & stylish
The door stopper is extremely compact and elegantly designed, easily fitting into a bag or pocket. We also provide a practical storage pouch so you can easily take it on business trips or vacations.
Fully compatible
This door lock is suitable for door gaps from 0.2 to 1.38 inches (5-35mm) and door thicknesses from 1.18 to 1.97 inches (30-50mm). Compatible with all floor types.
