When Square Is the Right Shape

Square covers are used where the underground opening is rectangular or where a larger access area is needed than round covers provide. Utility vaults, equipment chambers, and large-scale infrastructure access points typically require square openings for equipment passage and worker access.

Configurations

  • Lay-in lid — Standard removable lid for routine access
  • Hinged locking lid — Stays attached to the frame, locks in the closed position. Faster for frequent access and prevents the lid from being separated from the vault.

Available Sizes

Square vaults from 12”×12” to 48”×48” with depths from 9” to 48”. Call (866) 514-3684 for help matching dimensions to your installation.
