ABSTRACT:
The present invention relates, in one embodiment, to an apparatus for holding a door. The apparatus includes a body member and a blocking member rotatably coupled to the body member. The coupling is such that when the body member is positioned vertically in front of the door, the blocking member is disposed in one of a first blocking position and a second blocking position. The blocking member, in the first blocking position, contacts the door to hold the door at a first predefined position. The apparatus, when the blocking member is in the second blocking position, contacts the door to hold the door at a second predefined position. The door is opened further in the second predefined position than in the first predefined position.
