ABSTRACT:
A door stop is formed from a single flexible band of sheet metal which is symmetrical about a transverse center line and includes an arch shaped central section and two end portions. An underside of one end portion includes a high friction material while the underside of the other end portion is free from that material. The only engagement with the door is provided by the frictional engagement of a high friction material on a center section engaging the bottom edge of the door. The device can thus be used from either direction and provides a symmetrical force on the door preventing movement relative to the stop in either direction.
