Abstract: Wood-to-Metal Post Clamp with Adjustable Rail Bracket Angle (WTMPCWARBA), Set (A, B and C) comprised of two Galvanized Carriage Bolts and nuts; and 4 pieces of punched and press-formed from sheet metal (preferably galvanized); Two pieces formed as pipe clamping mechanism and two pieces as rail bracket to be connected to two wooden fence frame members (rails are 2×4s) to an elongated pipe member. These designs allow adjusting the angle of the rail brackets easily, independently and properly, based on land topology and property boundary path, and at the same time create a sturdy and durable wood-to-pipe connection ideal for hillsides. Moreover, this invention minimizes the overall fence footprint by a minimum of 1.5 inches (thickness of rail), and at the same time accommodates pickets to be installed continuously without a gap near the round posts/pipes.
