    摘要: A mounting member is provided with an alignment ring and a plurality of outwardly projecting posts unitary therewith. Each post has a threaded bore for receiving a mounting screw. The member is temporarily releasably secured within a mold with the distal ends of the posts displaced inwardly from an adjacent interior surface of the mold and with the openings of the bores directed towards the adjacent interior mold surface. An article is rotationally molded to encapsulate the member with at least the distal end portion of each post embedded in a formed wall of the article.
