2-IN-1 DOOR STOP ALARM & DOOR STOPPER – Blocks forced entry while the 120 dB siren scares off intruders and alerts people nearby; our door stoppers have a rubber wedge base that holds doors firmly in place for home and travel security.
LOUD 120 dB SIREN, NO INSTALLATION – Simply place the wedge under inward-opening doors; when pressure is applied the alarm sounds instantly and is audible to 1500 ft. No tools, wiring, Wi-Fi or setup required.
ADJUSTABLE SENSITIVITY LEVELS – Customize your protection with High, Medium, or Low sensitivity settings on your door stop wedge, depending on door clearance and environment. Works best with door-to-floor gaps between 0.6″ and 1.2″.
COMPACT, PORTABLE TRAVEL DOOR ALARM – Lightweight design fits easily in a suitcase, backpack or purse. Ideal for hotel stays, dorm safety, solo travelers, renters and anyone wanting extra door security.
BATTERY-OPERATED & RELIABLE PROTECTION – Runs on a standard 9V battery (not included) with low-battery indicator so your door stopper alarm is ready whenever you need added peace of mind.
