Add a portable door alert with this four-pack of black PocketLock door stop alarms. Each wedge combines a rubber base with a pressure-activated 120-decibel siren to help draw attention when a door presses against it. Designed for inward-opening doors, the alarm works best with door-to-floor gaps between 0.6 and 1.2 inches. Choose High, Medium, or Low sensitivity to suit the clearance and environment. Picture placing a wedge beneath your hotel room door before settling in for the night, then packing it into your suitcase when you leave. No tools, wiring, or Wi-Fi connection are required. Each alarm runs on a standard 9V battery, sold separately, and includes a low-battery indicator. Check floor grip, door clearance, and alarm operation before use. The compact design also suits compatible apartment or dorm doors. Keep the wedge accessible for removal, and ensure occupants know how to clear the doorway whenever they need to exit.
