You don't always want to keep internal doors closed and locked, particularly the nursery or bedroom door. Doors can present a danger to young children as they can easily trap their delicate little fingers in them as they slam shut. The Door Stopper acts as a cushion to prevent the door from closing or slamming into young children. It has the added bonus of preventing the door from banging loudly, which is especially useful if you've just put tired youngsters to bed. This is a premium, heavy duty version, made from soft grey flexible rubber. Use this door stopper on heavy doors and doors which are in constant use.
