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. ## Claims ### Claim 1 A jig for use in assisting orientation and fixing of an insulator to a support comprising: a jig frame comprising a top surface, and two sides that define an open volume; the two sides have parallel contact edges at ends of the sides; at least one of the two sides having an opening therein of at least 1.5 cm in diameter; 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; 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. ### Claim 2 (depends on 1) The jig of claim 1 having a securing element for temporarily securing the jig to a surface to be machined and the opening having a level indicator therein that indicates when the top surface is horizontally level. ### Claim 3 (depends on 2) The jig of claim 2 wherein the securing element comprises an attachment element on the jig between the two guide pipes. ### Claim 4 (depends on 2) The jig of claim 2 wherein the opening has a notch on its circumference or an inwardly facing post and the level indicator respectively has an extension fitting into the notch or a gap in the circumference of the level indicator that receives the post to align the level indicator perpendicular to the top surface. ### Claim 5 (depends on 4) The jig of claim 4 wherein the two guide pipes are each perpendicular to the top surface and the level indicator comprises a bubble level indicator and the level indicator is removable from the opening and is positionable within the opening only when a post and gap or a notch and extension are aligned. ### Claim 6 (depends on 5) A method of attaching an insulator to a support comprising: placing the jig of claim 5 against a surface to which the insulator is to be attached, orienting two contact portions with a top surface of the support, aligning guide tubes with specific positions on the support where connectors for an insulator are to be used to form an aligned position, adjusting the insulator so that the top surface is parallel to the a nearest surface of the support according to the level indicator;
