    Abstract: An EXTERIOR UTILITY GUARD that is a protector and or shield for low voltage irrigation wire and more particularly to protect the wires from lawn equipment, particularly weed and grass trimmers. It is made of heavy gauge metal, 14 gauge steel, to withstand repeated blows from weed and grass trimmers. It is long enough (16? + or ?) to extend both into and above ground level to protect the low voltage wires from the strike zone of weed and grass trimmers. It is designed with three elongated slots at the bottom to accommodate low voltage wires. It has four holes at the top sides to accommodate a mounting bracket. It is designed so it can be mounted over the irrigation wires and or PCV pipe without having to disconnect the wires from the control box. This design will reduce installation labor and cost.
