  • Patent number: 4818822
    Abstract: A junction box readily adapted for installation to an electric power cable made up of a pair of identical interlocking sections which are joined together over the cable at any appropriate point on the cable. In one embodiment the box is employed as a "stringer" box where a series of the boxes are installed on a single power cable. In such embodiment, hollow projections are provided at each end of the box for entry and exit of the power cable, the projections being formed by the pairing of clamping members in the end walls of the interlocking sections. Through the use of special reinforcing, the junction box is light in weight but can withstand heavy abuse.
