The Barricade is a craftable aesthetic block in Tinker's Construct.
Barricades are used for trading with Village Tinkerers
Oak (Birch, Spruce, or Jungle) Barricades are, and slightly defensive, purposes. They do not count as 1.5 blocks tall, despite looking like a fence, and so cannot keep mobs out unless 2 (8 Barricades) are stacked on top of each other. However, they are highly blast resistant, they can stack in-game holding up to 4 barricades in a single block, and they must be broken individually in order to be fully destroyed. Using these, you can make a wall that defends against TNT, mobs, and players (For a short while) .They also stack in the player's inventory with up to 64 in one slot.
