first and second elongate branch portions that extend from opposed sides of the central portion and that define first and second central axes that extend parallel to opposed substantially straight edges of the first and second branch portions and that are positioned at an angle less than 90° relative to the longitudinal axis of the central portion, the first and second central axes intersecting at an intersection point that is distal to a midpoint of the first thru-bore formed in the central portion, and that is proximal to a midpoint of the second thru-bore formed in the central portion, the intersection point being offset from the plurality of thru-bores.
