Birch Barricade

The Birch Barricade is a block added by Tinkers' Construct. When placed in the world, the Birch Barricade will take one block. However, Birch Barricades can be "stacked": another Birch Barricade can be placed onto the first Birch Barricade, up to four Birch Barricades, to make a structure similar to a Fence. Each Birch Barricade in a stack must be broken individually.
