A spring-operated doorstop for holding a door in an open position. The doorstop has a flat thin base plate for permanent attachment on a floor, and a top plate hinged to the base plate. A spring holds the top plate apart from the base plate, such that when the spring is in a non-compressed state, the angle between the base plate and the top plate is a set angle. A foot pedal is rigidly attached to the top plate. The doorstop is installed near the wall with the hinge facing outward, so that when the door is opened toward the wall and over the door stop, the spring momentarily compresses. It then springs back, so that the top plate will prevent the door from unwanted re-closing. The foot pedal may be used to hold the top plate down when the door is desired to be closed.

Disclosed is a doorstop assembly which allows a doorstop to be conveniently installed or removed from left or right swinging doors of varying thicknesses. The assembly has a portable door clip which may be easily pulled off a left swing door, turned upside down, and then pushed into place onto a right swing door.
