One of the bracket mounting holes is slotted to permit slight variations in mounting bolt spacing. The insulator mounting surface is at a height approximately 125mm above the top bracket mounting hole.

The pole top pin is made from hot new rolled steel. The steel will heat to red and punched to the designed shape. The finish of the pole top pin is hot dip galvanized which is reasonably smooth and free of burrs or other sharp projections.
