Wikipedia Wiktionary dictionary logo

  • A trapdoor is a door set into a floor or ceiling (depending on what side of the door one is on). Originally, trapdoors were sack traps in mills, and allowed the sacks to pass up through the mill while naturally falling back to a closed position. An exposed trapdoor could also be called a hatch, although hatches may be horizontal.
