Abstract: A door holder assembly used to maintain a door in an opened position. The assembly is made up of a door stop, a locking plate mounted on the door and a floor mounted door holder. The door stop and the door holder are fixed to the floor while the locking plate is fixed to the lower portion of the door and is positioned to engage the door holder when the door is opened. The locking plate has two joined segments one of which is planar and flat while the other of which has a right angled groove. Depending on the vertical elevation of the door's bottom above the floor, the same locking plate can be mounted to the door in one of two different positions. If the elevation is slight then the right angled groove portion is mounted on the vertical front door surface. If the elevation is larger and sufficient space exists, the locking plate may have the right angled groove portion mounted to the lower edge of the door between the door and the floor.
