Frequently Asked Questions

Q: How does the adjustable portable door stopper work?

A: The door stopper is wedged under the gap at the base of an inward-opening door. Its diamond-textured aluminum alloy base grips the floor firmly, preventing the door from being pushed open from the outside. No installation or drilling is required — simply slide it under the door and you're set.

Q: What floor types are compatible with this travel door stopper?

A: This door stopper works on most smooth and semi-smooth flat floors, including ceramic tile, hardwood, marble, and cement. It is not suitable for highly textured, uneven, or carpeted floors where a solid grip cannot be achieved.

Q: Is this door security lock suitable for hotel rooms?

A: Yes! The compact size (120 × 94 mm) makes it perfect for travel. It fits easily in a handbag, suitcase, or backpack, and works with the vast majority of standard hotel room doors that open inward and have a flat floor surface beneath them.

Q: What is the door gap range this stopper accommodates?

A: This adjustable door stopper is designed to work with door bottom gaps ranging from 5 mm to 35 mm, covering most standard residential and hotel interior doors.

Q: Will the door stopper damage my floors or door?

A: No. The stopper requires no drilling, adhesives, or permanent fixtures. The anti-slip base is designed to grip without scratching or marking most smooth floor surfaces.
