This portable steel door lock provides a firm extra layer of security for homes, offices, and travel stays. The steel insert slides into the door frame and the locking plate holds the door steady. It helps you secure your room during trips, short lets, hostels, or any space where you want more control. The design is compact and fits in a small bag or pocket. Setup is fast. No tools are needed. The lock works with many standard inward opening doors and supports your sense of safety in unfamiliar spaces.
