4'x4' Electrical Vault

Precast electrical vaults, also referred to as splice boxes and switchgear vaults, are the industry's leading product choice to protect and provide access to electrical cables and transformers, and are a preferred alternative to running electrical power cables above the ground and across utility poles. With standard and customizable options, these vaults are the perfect example of value-added engineering with preinstalled equipment and accessories saving time and money on your next project. Available features include grade rings & risers, lifters, pulling irons, drainage sumps, term-a-ducts, knockouts, as well as racking to best fit your project needs. Octagonal vaults are similar to one piece vault configurations typically consist of a base section and a top section for applications requiring non-confined access. The unique feature of octagonal vaults is that multiple vaults can be set in the same excavation in adjacent offset relation to receive cables from different lines.
