Very resistant (high explosion resistance) version of the vanilla fence. Made of iron. Cannot be placed directly on the ground in contrast to vanilla fences. Iron Fence must be attached to Iron Fence Pole or another Iron Fence. This block can be placed at a maximum distance of 8 blocks from the Iron Fence Pole, and if you want to build further, you must build another Iron Fence Pole along the way. It works a bit like a repeater for the redstone dust.
