ABSTRACT:
Method for making an acrylic support post for display fixtures such as shelf units and hang racks. The post comprises an elongated acrylic transparent or translucent member having a longitudinal channel formed along one or a plurality of the sides of the post, a longitudinal anchor plate disposed along the bottom portion of the channel, a longitudinal hollow standard having spaced locking slots along the front face thereof secured with the anchor plate, and a casting around the anchor plate and standard filling the channel to lock the anchor plate in the channel. The casting is formed of a material which blends with the acrylic of the post such as a methyl methacrylate resin and the like. The anchor plate is securely locked in place by the casting while the standard is secured with the anchor plate by means of screws. The channel is rectangular having radiused bottom corners. The casting is made in defined stages. The standard and anchor plate are secured together and positioned as a unit in the channel during the first pouring stage of forming the casting followed by the final stage of pouring the casting.
