Heavy Duty Alarm Door Stopper

Constructed from durable aluminum alloy, this door stopper is built to resist bending or breaking under pressure. It features a strong rubber suction cup base that adheres firmly to smooth floors — tile, hardwood or laminate — delivering reliable resistance against forced entry when engaged in guard position. The integrated vibration-sensitive alarm emits an 80dB audible alert upon tampering or attempted door movement, providing immediate awareness of intrusion attempts. Weighing only 220g and measuring approximately 12.5 x 6.5 x 4.5 cm (as shown), it is compact and lightweight for effortless portability. Installation and removal take seconds — no tools required — simply press down to activate or lift upward to disengage, making it suitable for adults and children alike. Designed for temporary indoor use on flat, non-porous surfaces.
