Interesting. Half of the people believe he means the vent for a cast
iron steam or hot water radiator, and the other half believe he's
referring to a floor register. Will the OP post again to clarify?
Wife and I bought all we could from Home Depot/Lowes, then for the one
odd-sized grate (the only floor cold air return in the house), we went
to "Reggio Registers".
Odd sized items from specialty stores will cost 5-10 times as much as
commodity items from HD or Lowes. Same manufacturer, and everything,
