Abstract
A gate hingedly connected to a staircase. The gate hinge is blow-molded integrally with the gate body. A mounting post has on one portion a hinge pin for receiving the gate hinge, and the other portion has a pair of parallel resilient sheets for receiving an edge portion of the staircase. Two staircases are attached back-to-back by vertical flanges each of which is offset from a vertical center plane of the respective back wall portion and has a vertical surface which is co-planar with the vertical center plane. The corners of the staircase are individually height adjustable by internally threaded portions which receive threaded rods. The internal threads are formed as part of the blow-molding process. A hole to the interior of the staircase or other article is formed as part of the blow-molding process.
