Buying Guide: How to Choose Door Stoppers

Door Stoppers: Portable Security for Anywhere

Hotel rooms, Airbnbs, dorm rooms, anywhere the door lock isn't quite trustworthy—portable door stoppers provide peace of mind.

Types of Portable Security

Floor-bracing stoppers:
  • Use friction against floor
    - Work on any door
    - Affected by floor surface (carpet vs. tile)

    Strike plate locks:
    - Insert into existing door hardware
    - Don't depend on floor
    - Need compatible strike plate

    Alarm wedges:
    - Combine physical block with siren
    - Alert even if block fails
    - Batteries required

    ### Travel Security Essentials
    - Hotel rooms: Staff have master keys
    - Airbnbs: Previous guests may have keys
    - Dorms: Communal living = reduced security
    - Visiting relatives: Unfamiliar locks

    ### What to Look For
    - Floor compatibility: Works on carpet AND hard floors
    - Door gap: Fits under standard doors (0.5-1.5" gap)
    - Portability: Light enough to carry, small enough to pack
    - Strength: Can withstand reasonable force
    - Alarm option: Bonus security layer
  • Frequently Asked Questions About Door Stoppers

    Do these work on outward-opening doors?

    Most floor-based stoppers only work on inward-opening doors. For outward-opening doors, use strike plate locks (Addalock) or portable travel locks that wrap around hinges.

    Can hotel staff still enter with these?

    That's the point—even master keys won't bypass a physical barrier. For legitimate access (housekeeping, emergencies), you'd need to remove it. Use the "Do Not Disturb" approach.

    Are these legal to use in hotels?

    Yes—you're adding security to your rented space, not damaging anything. However, in true emergencies (fire, medical), hotel staff may need to force entry. Use responsibly.
