This pin/bracket is installed so the insulator is horizontal - as shown. This is a 'perch' for hot clamps that the linemen use when working on the pole. This one had a cracked porcelain insulator on it that the lead on the pin had melted and was forced out along the crack and had formed a 1/4 inch long arrow pointing downward outside of the insulator. Dumbass Me took it apart for no good reason....

Had to have been a massive voltage surge to melt the lead as shown.
