The Allied Tube & Conduit PVC Conduit (vendor part 8524, Millennium part 524497) is a 6 in, 20 ft gray section built to UL651 standard, sized for large-capacity duct bank runs feeding multiple fiber or power cables between vaults and cabinets. The 20 ft length reduces the number of joints crews need to make on long trench runs. UL651 compliance keeps the installation code-compliant for buried and exposed electrical raceway. Millennium also stocks matching 6 in couplers, elbows and end bells for the same duct system.
