Iron Trapdoor
Iron Trapdoor opens only by redstone signal — the secure horizontal hatch for vault floors and zombie-proof tunnel covers.
Description
The critical mechanical difference from wooden trapdoors is that this variant cannot be opened by right-clicking. Players must apply a redstone signal to make it swing — from a button, lever, pressure plate, or detector circuit. This makes the metal version the secure choice for vault hatches, hidden bunker entrances, mob-trap floor mechanisms, and anywhere a wooden trapdoor's openness would be a liability. Like all metal blocks, it does not burn and survives lava and direct fire contact undamaged. The block can be combined with iron doors and trapdoors for fully redstone-controlled entry systems where no manual interaction is possible.

How to use an Iron Trapdoor in Minecraft
-
1
Craft the Iron Trapdoor
Place 4 iron ingots in a 2×2 square on any crafting grid — the player's 2×2 inventory grid or a crafting table — to receive 1 Iron Trapdoor.
-
2
Choose a placement surface
Right-click any solid block face to attach the Iron Trapdoor. It snaps to the top or bottom half of the block and hinges on the edge closest to you.
-
3
Connect a redstone power source
Place a button, lever, pressure plate, or tripwire hook adjacent to or directly below the trapdoor. An Iron Trapdoor opens only when it receives a redstone signal — right-clicking does nothing.
-
4
Activate and test the mechanism
Trigger the power source to swing the Iron Trapdoor open 90 degrees. Release the signal and it closes automatically. Test from both sides to confirm it works as a passage.
-
5
Add a delay for timed closing
Insert a redstone repeater set to 1–4 ticks of delay between the power source and the trapdoor to create a door that closes automatically a fraction of a second after activation.
No mob — not even villagers — can open an Iron Trapdoor. This makes it the only manual-entry-proof horizontal hatch in vanilla Minecraft, suitable for secure sorting rooms and mob farms.
