KEEPS YOUR CHILD SAFE - When your little ones start to walk, it is the time to childproof the places that are not safe for them. Our child door knob covers help keep infants from opening doors and entering/leaving rooms. UNIVERSAL & SPECIAL DESIGN - Our child proofing knob covers are specifically designed that blends easily with home decor. The double button design lock increases friction with the doorknob, making easy for adults to open the door. COMPATIBLE WITH MOST DOORKNOBS - These baby proof door handle locks perfectly fit with all standard spherical doorknobs. Due to their large size, they spin in hands to prevent a child’s grip but provide easy access to adults. EASY TO INSTALL/REMOVE - Unlike other toddler door locks, they require no drill or tools to install. Simply put the two covers together on the doorknob, and close them. They are installed now. Use a screwdriver to remove the lock. SATISFACTION GUARANTEED - Made of Eco-friendly PP and TPR material, our protective locks provide lifetime money-back guarantee and can be returned with no questions asked. Order now to keep your child safe and put your mind at ease.
