Why you need it: No more children or pets locking you or themselves in a room; preventing children from entering certain rooms like toilets or storage rooms without adult supervision; preventing children from playing with doors and pinching their fingers. Upgraded Double Lock System: The childproof door is designed horizontally with a double lock system that stops children or pets from opening the door, keeping them in a safe place. Child safety locks provide children with a safe childhood. Wide application and anti-lockout: Door-level locks are compatible with most standard door-level handles. A safety lock prevents you from being locked out by children. Easy to install and remove: No tools and screw drilling required. Simply peel and stick the 3M adhesive to install the security door lock. To remove, heat the baby lock with a hair dryer for about a minute, then carefully peel off the glue. Safe and Durable: The lever handle lock is made of non-toxic ABS material. The durable handle lock is sturdy enough for small children to beat or remove, ensuring your child has a safe place.
