A rather complex, intricate Gordian Knot backplate design for a humble All Wire Metal Plat Scan Hook – check the inset photo for the unique over- and under-lap welds.  The long upward tines would also seem to make it a challenge to insert and remove from this tight Grid or Slatwire, though it would certainly resist tampering and jostling from the public. Extended tines like this are most often seen in Corrugated Hooks, though in a smaller gauge. Though dark contrasting hooks, they did not overly fight the display.
