Portable Alarm Door Stopper

A self-defense portable door lock (often referred to as a "lock stop") is a bright red, compact safety device engineered to physically reinforce inward-swinging doors from the inside. By wedging into the door strike plate, it creates an impenetrable mechanical barrier that prevents forced entry, even if an intruder possesses a physical key.

Key Features

High-Visibility Red Finish: The distinct bright red color serves as an easy visual indicator for fast installation during low-light conditions or stressful emergency situations.Dual-Size Strike Claw: Built with a durable carbon steel or stainless steel plate featuring two distinct slot sizes to universally fit standard residential and commercial latch openings.Tool-Free 3-Step Setup: Installs in under three seconds by inserting the metal claws into the strike frame, closing the door, and sliding the red wedge knob into the alignment slot.Downward Force Distribution: Engineered so that external attempts to force or kick the door open actually push the internal red locking block tighter against the frame, locking it firmer in place

Pocket-Sized Portability: Extremely lightweight (typically around 200 grams), it fits seamlessly into a backpack, handbag, or carry-on travel pouch.
