Oww. The folding style closet doors? I still remember crushing a finger in that kind when I was in kindergarten. When we moved into this house, this bifold door lock was one of our first purchases, since we wanted to be able to keep our toddler out of the laundry closet. (We put them on the bedroom closet doors, too, but obviously that prevents them from getting into their own closets — which works for us since their dressers are outside their closets, but I know that doesn’t work for everyone.)
