Abstract: A wedge post-base system for adjusting the orientation of an attached post relative to a mounting surface is disclosed. The base utilizes a two-piece structure, each piece having an angled mating surface relative to an opposing surface which allows a central axis of a post mounting collar to be altered, and thus the angle of the post itself. The resulting angle addresses the issue of mounting posts on a sloped plane. A fencing system having hinged railings and balusters as well as a railing system having a hinged upper rail are also disclosed.
