ABSTRACT A chain door guard assembly is disclosed which includes a guard plate having a raised main body section and extending flanges for attaching the guard plate to a door. The main body section of the guard plate defines a long slot and a plurality of entry slots which permit insertion of a plurality of chain heads into the long slot. Two independent entry slots, one in the form of a vertical slot, for accepting a chain head in one instance and a chain-attached slide bolt in the other, are also provided. The insertion of the slide bolt attachment into the opening at the end of the long slot adjacent to the jamb is restricted by an ambutment on said slot, while beyond said abutment, the long slot extends past the plurality of the entry slots into it and past the main slot into the vertical slot. The assembly is completed by a bracket to which the chain is rotatably anchored, for attachment to the door jamb. The resulting chain door guard assembly affords selectively varying degrees of security and convenience, achieved by the insertion of various chain heads into various entry slots. (It should be noted that this chain door guard has four entry slots and but two chain heads and a sliding bolt which are linked in this interlocking ?nnovation to provide a variation of safeguards up to the utmost security, with the force of a bolt and a bar).
