Abstract
A jig enabled method of attaching structures such as insulators to support. The jig has: a jig frame comprising a top surface, and two two sides have parallel contact edges at ends of the sides; the top surface has two holes passing through the top surface; within each of the holes is a hollow guide pipe passing from an exterior surface of the top surface through an interior surface of the top surface; and the hollow guide pipe passing past the interior surface of the top surface a distance that is less than a distance to plane formed by the two parallel contact edges. At least one bubble level may be oriented parallel to a surface on the jig and/or parallel to an edge of the jig.
