Product Details
Everything you need to know — features, specs, fitment, and answers to the most common questions.
Physical block plus alarm
The wedge resists the door opening while the siren announces the attempt — deterrence on two fronts.
No tools, no damage
Slides under any inward-opening door in seconds. Nothing to install, nothing to mark up a rental.
Travels anywhere
Compact enough for a carry-on or backpack — hotels, dorms, apartments, Airbnbs.
Lifetime warranty — no receipt
Alarm or wedge fails under normal use, we replace it.
- Does it work on carpet and tile both?
- Yes — the base is designed to grip hard floors and carpet. On very thick carpet, press it firmly against the door bottom so the wedge engages before the alarm plate.
- Warranty coverage?
- Lifetime warranty. If it fails under normal use we replace it — no receipt, no questions.
- How fast will it arrive?
- Same-day dispatch from Columbus, OH on orders before 2pm ET. Free standard shipping over $49.

Peace of mind in every rental
I move between short-term rentals for 13-week contracts. This wedges under the door in seconds, and the alarm is genuinely loud — tested it once and my ears rang. No tools, no marks on the door, fits in my carry-on.

Standard kit for hotel nights
150 hotel nights a year. This goes under the door every night — the wedge alone physically resists the door opening, and the siren would wake the whole floor. Cheap insurance for anyone who travels alone.

Dorm room confidence
Use it in my dorm since the lock is ancient. Setup is literally wedge-and-go. Test the alarm sensitivity when you first get it so you know what triggers it — mine needed a firmer bump than I expected, which honestly avoids false alarms.
