ABSTRACT:
A meter socket jumper assembly comprising a plastic disc having a diameter and an edge thickness substantially the same dimensions as a meter of the type designed for assembly in said socket. Said disc is provided with a series of integrally molded pockets shaped and dimensioned to receive a fastener such as a self tapping screw from the rear side to retain a jumper bar on said rear side. Said pockets are so designed that the self tapping screw assembled therein is not exposed on the front face of the disc. In a preferred embodiment of the invention the pockets protrude from the front of the disc and intersect stiffening ribs molded into the face of the cover, to strengthen the pocket walls against the expansive force of the fasteners inserted therein from the rear side.
A plurality of pockets are provided, suitably spaced to allow the assembly of jumpers in several different predetermined positions to accomodate different types of meter sockets.
