Effective security with no installation
Combine sturdy door security with a powerful alarm in one compact device. Simply slide this security wedge under the door – no screws, wiring, or installation required. As soon as someone forces the door, the vibration sensor detects it and activates a 120dB siren. You get an instant audible warning, wherever you are in the house. Place it under any door, choose your preferred sensitivity level, and use it as a regular door wedge when the alarm is off.
Benefits of this door security device

- Three sensitivity settings: choose H (high), M (medium), or L (low) for optimal detection
- Universal fit: fits under any hinged door at home, in a hotel, dorm, or office
- No tools required: ready to use in seconds, ideal for home and travel

We staan achter elk stuk dat we verkopen
We begonnen Sulvida vanuit één overtuiging: wonen mag tijdloos én betrouwbaar zijn. Elk stuk in onze collectie kiezen we persoonlijk uit op kwaliteit, materiaal en afwerking. Voldoet het niet aan onze eigen standaard, dan komt het ook niet bij jou terecht. Dat is geen beleid — zo werken we gewoon.
