SECURITY AND PRIVACY - This portable door lock provides you with extra security and privacy, significantly enhancing your safety and preventing unauthorized access. The door cannot be opened from the outside, not even with a key; this is very helpful for you when you are on a business trip, traveling, or living alone. USER-FRIENDLY - This security door lock is easy to install and remove and can be installed in seconds without tools, even in emergencies and in the dark. Place the metal part of the door lock into the door frame's strike plate, close the door, and then place the handle's groove against the doorpost on the metal plate. No one can then open the door from the outside. STRONG LOCK - The security door lock is made of strong stainless steel. The robust ABS plastic casing prevents damage to doors under pressure. Steel surfaces with galvanic and polishing technology ensure a smooth feel and minimize skin damage. A strong, high-quality door lock guarantees a longer lifespan. VERSATILE - The security door stop has two holes of different sizes, allowing all types of door locks to fit together. Perfect for hotels, student housing, apartments, short-term rentals, bathrooms, bedrooms, or private rooms. It can also be used to prevent pets from going out and to prevent children from opening their door to strangers. Portable door lock - Dimensions: 13 x 4.2 x 1 cm with 2 cm and 3 cm holes. Lightweight and small, fits in a pocket or handbag. Only suitable for inward-opening doors with a gap less than 2 cm.
