Structuralduct

The Structuralduct is a block from Thermal Dynamics used to create Covers. They can connect to other Ducts, but will not transfer items, fluids, or energy.

A Structuralduct can be crafted with any block or fluid bucket to create six Covers of that block. The Covers can be placed on other Ducts to conceal them or give flat surfaces to walk on. Ducts can still connect through Covers.
