| Perpendicular diamonds |
This cast iron 15 x 15 cross diamond pattern utility cover is seen in the street beneath our feet.
This is a Model SCM-5 cover made by Fairfield Industries of Georgetown, South Carolina. It is part of a spill containment manhole that contains any spills that may happen while filling underground storage tanks.
Seen to the left is a 5 x 'lots of holes' cover for a rain drainage system.
