摘要： An electrical underground wire pulley for pulling wire through conduit having an opening in a base structure that is provided with pre-installed anchor bolts. The wire pulley includes a frame with a bottom adapter plate and a pair of side supports extending upwardly from the adapter plate. The adapter plate includes an opening through which the top of the conduit extends, and a set of four slots through which the anchor bolts extend for securing the wire pulley to the base. The slots are equally spaced from one another and extend lengthwise at 90 degrees radially outwardly from the conduit opening to accept anchor bolt patterns of different size. A pulley is rotatably supported between the side supports above and offset behind from the center of the conduit to assist in pulling wire through the conduit.
