Risers and Grade Rings
Precast risers and grade rings adjust vaults to match finished site grade. These components simplify installation, allowing contractors to adapt quickly to varied site conditions.
Pulling Irons and Conduit Openings
Integrated pulling irons, knockouts, and conduit penetrations make cable pulling and system integration easier. Many of our pull boxes and handholes also feature preinstalled snap-in clips to eliminate the need for lock nuts and washers in the field.
Ladders and Safety Hardware
For safe interior access, vaults can be outfitted with steps, ladders, and interior racking. These features improve worker safety and streamline ongoing maintenance.
Utility Vault Accessories
Additional options such as drainage sumps, lifting anchors, inserts, and racking systems extend vault functionality and help safeguard against copper theft. For added protection, our LockLid™ system prevents pry-bar access to covers, delivering a proven defense against unauthorized entry and copper wire theft.
