The B165 and B165R Grounding Receptacles are copper alloy castings intended for use in static grounding systems of aircraft refueling areas. They are easily connected to the grounding system conductor and/or ground rods with CADWELD connections. Designed for simple installation flush with the paved surface. The attachment point (3/4" ball) is an integral part of the casting on the B165 and is removable on the B165R.
