ABSTRACT:
A device for reducing the spacing between the lock side of a door and an adjacent member, such as another door or door frame, should the spacing between the member and lock side of the door increase to a point where the fire rating of the door and member is adversely effected. A generally L or U shaped metal edge guard is mounted by machine screws to metal studs which are threadably fastened to the lock side of the door. The spacing between the edge guard and lock side is varied by adjusting the position of the studs within the lock side of the door.
