Door Guard

The Guard Dog, a portable door guard with siren alarm from Blockit & Lockit Systems, self-assembles in seconds and can be folded for storage. A 9-volt battery powers the 120-decibel siren alarm that sounds when the motion sensor detects activity. The motion sensor can be set to high or low sensitivity and the on and off switch prevents accidental sounding. Made of structural resin with a steel leg, the device prevents the door from opening and non-skid foot grips most floor surfaces.
