A removable torque rod assembly for a self-closing door which may be easily installed on a door and an anchoring device mounted to an underlying door frame. The torque rod assembly may be used for either a left- or right-handed door. The assembly uses a torque rod located inside a metal sleeve having the sleeve crimped or attached to or otherwise made integral with the rod at its top end so that the rod and sleeve act together at the top end. The lower end of the torque rod passes through a bushing attached to the sleeve and through a bushing cap surrounding the bushing. A resilient O-ring fits into an annular groove in the bushing. The torque rod assembly is installed on the door by forcing the O-ring past an aperture in the door so that the O-ring holds the assembly on the door and a head of the bushing mates with the aperture in the door. The lower end of the torque rod assembly is then mounted in an anchoring device which keeps the lower end of the rod from rotating. The upper end of the torque rod is not attached to the door or frame and is a free end. The torque rod assembly may be removed from the door by lifting the door in order to dismount the lower end of the assembly from the anchoring device and then pushing the lower end of the assembly downward until the O-ring slips free of the aperture in the door.
