KERUI 2-Pack Wireless Door Stop Alarm System

Shield your personal space with dual-layer security. The KERUI system functions as a heavy-duty doorblock and a motion-triggered siren. The stainless steel cover resists dents and wear, while the non-slip base keeps the wedge anchored during use.

You can deploy it in seconds anywhere you travel. The compact size slips into luggage, bags, or drawers, making it a reliable companion for business trips, remote work, or family safety.
