Keeping little ones safe is a top priority and doors are a major part of babyproofing. The KidCo Door Knob Lock helps prevent toddlers from opening doors and leaving a room or going into a room unsupervised. It snaps tightly around the door knob and does not require any dismantling of the knob. The drop down pinch grips make it more difficult for toddlers to manipulate as they can't just cup it and turn. Available two to a pack in White. Door Knob Lock easy installation door protection
