An integral riser structure for a watt-hour meter enclosure to provide a mounting structure for a pair of meter jaw assemblies includes a pair of laterally spaced riser walls formed integrally with a back wall of the enclosure and positioned in forwardly spaced relation to the back wall. The riser walls are separated by a recessed wall positioned in a recessed plane located between the plane of the riser walls and the plane of the back wall. The riser walls include holes to receive fasteners to secure the meter jaw assemblies to the riser walls.
