Abstract: A door stop for a door includes a clamp that is securable over a first side edge of a door. The clamp has a guide. An arm has a receiving portion for receiving the guide to permit movement of the arm on the clamp between an open position and a closed position. A spring mechanism is operably coupled to the clamp and the arm, and urges the arm on the guide of the clamp toward the closed position. In the closed position, the arm prevents the door from engaging with a respective door jamb.
