Abstract
Abstract This conduit locator is designed to indicate the location of an end of a conduit after concrete is poured over the conduit. Primarily, it consists of an adhesive tape having a multiple number of spaced rods adhered so as to extend from an edge of the tape, and the tape is adhered to the open end of the conduit which may be plugged or covered with out interfering with the rods extending upward. The rods are of a springy plastic and protrude upward after the concrete is poured over the conduit enabling the end of the conduit to be located beneath the surface of the concrete.
