Recognition From Other Mods
It is recognized as a chest by other mods, therefore it can receive items from BuildCraft Pipes. However, it cannot actually push items into a BuildCraft pipe. Thus it can serve as a possible link between BuildCraft Pipes and RedPower Pneumatic Tubes.
When presented with a redstone pulse, it will eject a single item. It is also capable of ejecting directly into inventories and other chests. This includes Industrial Craft machines.
