Abstract: A fence support member to attach to an existing fence post or wall, the support member including an elongated support arm and a fastening assembly to fasten the support arm to the fence post or wall. The support arm has spaced slots or holes therein to receive and retain strands of wire or fencing. The support arm has a first end which is designed to abut the existing fence post or wall. The first end includes first and second abutment surfaces which are located on the edge of the first end of the support arm. The abutment surfaces are at an acute angle with each other. The fastening assembly includes a pair of L-shaped brackets, one positioned on each side of the support arm and a U-bolt which is employed to attach the brackets to a fence post. The support arm can be attached to a fence post or wall such that the support arm extends parallel or at an acute angle to the fence post or wall, depending on which abutment surface is in contact with the fence post or wall.
