Lock Door Stopper: Unmatched Security Most door locks can be easily opened by the young, failing to provide the security you truly need. Our innovative lock, however, requires an adult to press the buttons on one side of the lock, ensuring enhanced protection. EASY OPERATION - Designed for convenience, both men and women can effortlessly open and close the door with just one hand. With only two fingers, you can operate the lock. Simply press the unlock button to deactivate one side. To fully unlock, press the two-sided button, which also prevents accidental self-locking. SUPER EASY INSTALLATION - Say goodbye to tools and drilling. Our lock adheres to your door using the included 3M adhesive backing. Should you need to remove the lock, just heat the 3M sticker with a hairdryer for easy removal, leaving no damage or marks on your door. IMPROVED DOOR LEVER LOCK - No more worries about being locked in a room by kids. The Door Lever Lock can only be locked and unlocked by pressing the buttons. Made from upgraded ABS material (20% PC mixed for added hardness) and superior 3M glue (17N / 100MM), this Lever Door Lock is durable and not easily broken or removed by children, ensuring your family’s safety and peace of mind.
