Two layers of protection—a physical wedge that blocks the door PLUS a 120dB alarm when pressure is applied. The loudest door alarm available, combined with entry prevention.

  • 120dB alarm - Loudest door alarm, pain-threshold volume
  • Physical barrier - Wedge prevents door from opening
  • Floor wedge design - Slides under any inward-opening door
  • Non-slip grip - Stays in place under pressure

The door stop alarm provides two layers of protection most travel alarms don’t: it physically blocks the door from opening while simultaneously sounding a 120dB alarm. Even if someone has a key, they can’t get in easily.

Dual Layer Protection

Most door alarms just alert you. This one blocks entry. The floor wedge physically prevents inward-opening doors from opening while the 120dB alarm sounds. Even someone with a key or master key faces a physical barrier.

Loudest Available

120dB is the threshold for hearing pain—genuinely loud enough to wake you, alert neighbors, and make any intruder extremely uncomfortable. This is the loudest door alarm in the lineup, providing maximum alert when triggered.

Frequently Asked Questions

Does it work on outward-opening doors?

No—the wedge only blocks inward-opening doors. Most hotel and residential bedroom doors open inward. For outward doors, use the Door Guard hanging alarm.

How loud is 120dB really?

It’s the threshold for hearing pain—like standing next to a jackhammer. Loud enough to wake you from deep sleep and disturb anyone nearby.

Can someone just push through it?

The wedge creates significant resistance. Combined with the 120dB alarm, most intruders will abandon the attempt rather than push through while drawing attention.
