ABSTRACT:
A readily adjustable door closure for varying the rate of speed at which an associated door may close which is effected by rotating the piston rod relative to the piston and associated cylinder assembly so as to vary the rate of flow of an actuating fluid flowing from one side of the piston to the other side of the piston, which controls the door closing speed accordingly.
