Adapters

Pin hole adapters or centering washers are used with 5/8-inch diameter shank steel pins on wood crossarms previously drilled with 1-1/2-inch holes for wood pins. The adapter top is placed in the top of the pin hole and is held in place by a circular rim at the top. The bottom adapter is placed in the bottom of the pin hole to center the pin shank and provide a firm bearing surface for the nut. They are hot dipped and galvanized to prevent from weathering. Aluminum adapters are designed for reliable terminations of aluminum and copper conductor in mechanical connectors. This eliminates bi-metalic corrosion. Aluminum compression adapter applications include mechanical connectors in molds case circuit breakers, panel board equipment and meter sockets.
