Fiber Optic Vaults 

Fiber optic vaults are hollow 5-sided hollow rectangular structures that are topped with concrete and an access lid. They are placed underground and provide housing and access to fiber optic splices and cabling. Precast vaults provide superior security and protection against vandalism and harsh weather while providing access to those who need it.  We offer one piece, three piece, and multi-piece vaults that can be customized for your project.

Vaults have a wide variety of uses and are cast in multiple sizes and designs.  For further customization, they can be cast with various features including grade rings / risers, lifters, pulling irons, drainage sumps, term-a-ducts, knockouts, and racking as needed.
