Ultra-Sensitive Alarm Protection

This portable door wedge is an industrial-grade door security device that prevents forced, unwanted entry. Its highly sensitive vibration sensor triggers the alarm at the slightest movement, protecting your sleep and peace of mind. Perfect for hotel rooms, public buildings, schools, and offices—giving you absolute security wherever you go.

Reinforced, Heavy-Duty Design

Made from thick aluminum alloy, this upgraded door stopper is shatterproof and built to last. Its high-quality rubber base grips the floor firmly and resists wear, while the clever wedge design uses leverage to block the door against any break-in attempt—giving you a truly worry-free, secure feeling.

Simple, Tool-Free Installation

No tools required. In just seconds, slide the wedge into the gap under an inward-opening door. Position it directly beneath the door handle and adjust the foot so it holds firmly against the floor. In case of emergency, the lock releases instantly with a quick upward motion. Tip: test the fit on your door beforehand to make sure it holds securely.

Compact & Travel-Friendly

The SentryWedge™ is compact and elegantly finished, small enough to fit in a bag or pouch. A convenient storage pouch is included, so you can carry it with you anywhere—on business trips or on vacation.

Fits Almost Any Door

Designed to work with door gaps of 0.2–1.38 in (5–35 mm) and door thicknesses of 1.18–1.97 in (30–50 mm). Compatible with all floor types.
