Improved double lock system: The child safety door lock is designed with a double lock system to prevent children or pets from opening the door and keep them in a safe place. Child safety locks are the perfect way to have a completely safe childhood. Wide range of applications and anti-locking: Door handle locks are compatible with most standard door handles. With 2 side buttons to manage the "disable" mode, the safety lock prevents you from being blocked by children. Easy to install and disassemble: you don't need any tools or drilling. The security door lock can be installed using a simple 3M peel and paste adhesive. To remove it, heat the baby lock with a hair dryer for about one minute, and then gently remove the glue. Safer and more durable: The wrist lever lock is made of non-toxic ABS material. The durable wrist lock is strong enough for small children to unlock or remove it, ensuring they have a safe place.
