ABSTRACT:
An assembly is arranged to include a tensioning means mounted within a housing structure. The assembly attaches to the head of an installed door hinge pin in order to store energy into such attachment to cause the door to close after having been opened then released, by reason of extended ends of the tensioning means interacting against the opposing door and wall.
