Product details
Description
Add an extra layer of security wherever you stay. Designed for hotel rooms, dorm rooms, apartments, bedrooms, and other indoor spaces, this compact device works as both a pressure-activated alarm and a standard door wedge.
Two Functions in One
Turn the switch ON to activate the alarm. When the door applies pressure to the metal plate, the device produces a powerful 120 dB alert.
Turn the switch OFF to use it as a regular door stopper without activating the alarm.
Powerful 120 dB Alert
The loud alarm is designed to draw attention and help discourage unauthorized entry, giving you additional awareness at home or while traveling.
Three Adjustable Sensitivity Levels
Choose from High, Medium, or Low sensitivity to suit different doors, floor surfaces, and environments.
Portable and Easy to Use
Weighing approximately 4.7 oz (133 g), the alarm is compact enough to carry in a suitcase, backpack, or travel bag. No tools, drilling, wiring, or permanent installation are required.
Simply install a 9V battery, select the desired sensitivity, switch the alarm on, and position it behind an inward-opening door.
Durable, Non-Slip Construction
The alarm features a stainless-steel pressure plate, durable plastic body, and anti-slip rubber base. The rubber bottom helps the wedge stay securely in place when pressure is applied.
Door Compatibility
This door stop alarm is designed for inward-opening doors.
Before purchasing, measure the clearance between the bottom of your door and the floor. The recommended door gap is:
0.39–1.38 inches (10–35 mm)
Test the alarm before each use and replace the battery if the alarm sound becomes weak or stops working.
This product provides an additional alert and deterrent. It is not a replacement for a properly installed door lock or other appropriate security measures.

FAQs
Please read our FAQs page to find out more.
Can it be used on outward swinging doors?
No, the Door Reinforcement Lock only works on inward swinging doors (doors that open into your home).
Does it require any special tools?
Yes, the Door Reinforcement Lock requires two tools for installation:
Electric drill – to make pilot holes
Screwdriver – to install the screws
Installation Details:
Takes about 5 minutes to install
Comes with 8 screws total (four 1" screws, four 2" screws, and four expansion screws to fit different door types)
You'll mark the position, drill pilot holes, and screw it into the door jamb
Is this lock weatherproof?
The product information for the Door Reinforcement Lock doesn't specifically mention weatherproofing or outdoor use. However, since it's made of aluminum and designed for inward-swinging doors, it's typically used for interior home security rather than exposed exterior applications.
What I know:
Material: Aluminum construction
Best for: Indoor doors (front/back entrances, interior rooms)
Durability: Customers report it feels solid and well-built
Important consideration: If you're planning to use this on an exterior door exposed to weather (rain, snow, temperature changes), you may want to verify with the manufacturer first, as the product description focuses on home security rather than weatherproofing.
Does it come with a manual?
Yes, it does come with instructions for installation.
Is installation hardware included?
Yes, it does come with instructions for installation and the necessary hardware.
