The World's Best Door Stop!The Jamm Door Stop's unique curved surface allows it to hold both sides of the door at the same time - stopping the door moving in both directions - whilst allowing it to grip all floor surfaces. The door cannot move in either direction and so little fingers cannot be trapped either at the handle or the hinges. Whilst an adult can easily put in place and remove the Jamm Door Stop, a child will not have the ability to remove it.The Jamm Door Stop is proudly made in the UK using recycled plastics and is available in 5 colours.
