1Double Door Compatibility: Worried about your kids damaging your closet or pinching their fingers while closing the doors? We help parents protect their little ones' fingers. Our child safety lock is designed for bifold doors, such as cabinets or storage areas, with sliding double fold locks to prevent accidents and unauthorized access to potentially dangerous areas! 2Extended Slide Support: Unlike plastic options in the market, this lock is made with eco friendly premium aluminum alloy, featuring sturdy dual sided extended handles that fit most bifold doors, hallway closets, and cabinets, without worrying about wear and tear over time! 3Easy to Use: No drilling or installation required, simply slide the lock to the center of the doors to secure it. With handles on both sides, this lock is versatile for doors of various thicknesses. Please check the door thickness before purchasing, suitable for bifold doors with a thickness range of 1 1/8in to 1 3/8in. 4Keep Cats and Dogs Out: Pets have learned how to open doors, closets, and pantries, only for you to come home to blankets on the floor, torn food bags, or spilled detergents. Just slide the lock bracket onto the door and slide it onto the joint to prevent the door from opening. 5Enhanced Safety: Kids love to explore their surroundings. They may be curious about closets, storage rooms, patios, balconies, decks, or pools behind sliding doors. To prevent children from opening sliding doors without your knowledge, a sliding door child lock will be a helpful solution to ensure their safety.
