Abstract: The invention is directed to a fence post and a modular fencing system and method that utilizes same. The fence post has an elongated body having an outer wall and at least one elongated channel defined by said outer wall. The elongated channel has opposing sides and an open front. A fastener guide is defined in the outer wall along a plane that is generally orthogonal to the opposing sides of the component channel. In a further embodiment the component channel includes a lip protruding inwardly from the opposing sides adjacent to the front portion. In a further embodiment the fencing system includes post reinforcement members and rail reinforcement members. In other embodiments a fencing system is provided which includes posts, rails, pickets, screens and spacers that interconnect with the aid of fasteners to define a fence structure.
