Key Features

Why specify this

  • Mid-size opening for utility vault access

  • Light enough for two-person field service
Overview

A common mid-size telecom and electrical vault configuration. The 28” round opening accommodates standard rack-pull and pedestal-service access, while the 32” overall frame OD gives enough surrounding flange to seat cleanly into a precast or cast-in-place vault top.

Marking and color options are configurable for utility-standard identification (e.g., COMMUNICATIONS, ELECTRIC, FIBER, etc.).
