"A conveyor piece used for seperating different levels of conveyor."
The Two-Level Corner is a Rare-tier conveyor that is basically a conveyor corner attached to a raised-ier conveyor. It is used to separate the flow of ore at different levels and can be used in conjunction with the Two-Level Conveyor.
It can also be used with the Ore Replicator so that ore that passes along the higher section will be copied and the new ore will travel along the lower level. This set-up is useful for using multiple furnaces.
