The plastic unit includes internal walls and internal openings between the sleeves, so that each two-by-four received in the horizontal sleeves is in direct wood-to-wood contact with approximately half of the butt surface of the vertical two-by-four, so as to directly transfer vertical forces there between, without the joiner unit being subject to such vertical forces. Several variations of such joiner units are disclosed for different types of corners, as is a framework made from such members and two-by-fours.
