ABSTRACT:
An expandable stop ring slides over the end of a top post until it engages a selected one of a number of spaced apart grooves in the end of a top post. The end of the top post is inserted into a bottom tubular post until the stop ring fits inside a keeper that is mounted to the upper end of the bottom post. The keeper prevents expansion of the stop ring, hence the stop ring and keeper combination support the top post and any equipment carried thereon. The top post height adjustment is made by lifting the top post to remove the stop ring from the keeper, thereby permitting sliding movement of the stop ring to another selected groove on the top post.
