Window & Door Alarm Sensor – 90dB, Batteries Included

Want to know when a door, window or cabinet opens? This small two-piece alarm sticks on with tape. When the magnet piece moves away from the sensor, it chirps loudly. It's a simple way to keep little ones out of the medicine cabinet, or to hear the back door open.

• 90dB alarm: rapid chirping you'll notice right away.
• Peel-and-stick: double-sided tape included. No wiring and no tools, so it's renter-friendly.
• Batteries included: ready to use out of the box.
• Lots of uses: doors, windows, and medicine or gun cabinets.
• Low profile: lightweight plastic that sits flat on the frame.

Good to know: made by LJG.
