Iron Fence (IndustrialCraft 2)

The Iron fence is a new type of fencing added by IndustrialCraft 2. Its functions other then being used as a fence are:
 * It can be used as a pole to slide down, faster then a ladder, slow enough for safe descent. To use it for this, approach it while sneaking.
 * If powered by a Magnetizer it will serve as an elevator if the player wears metal shoes near it.
 * It can be used to reinforce an Iron Scaffold
 * It is used to collect lighting power for the GregTech Lightning Rod.
