<p>A coupling assembly for coupling a post first section and a post second section to each other, the coupling assembly comprising: a first support member, the first support member defining a first member post attachment for attaching the post first section thereto; a second support member, the second support member defining a second member post attachment for attaching the post second section thereto; a pivot provided between the first and second support members for pivotally coupling the first and second support members to each other so that the first and second support members are pivotable about the pivot to change an angular relationship between the first and second support members; and a lock for locking the first and second support members in a substantially fixed angular relationship relatively to each other.</p> |
