The Channell Commercial ACC7734GY-131 handhole assembly (Millennium part #528284) provides a rugged, gray composite below-grade enclosure for protecting fiber optic and copper cable splices, slack loops, and terminations. Its traffic-rated design resists cracking under vehicle and pedestrian loads while the sealed, non-metallic construction eliminates rust and corrosion typically seen in cast iron handholes. The custom logo cover gives field technicians and locate crews a quick visual reference before excavation or access. Millennium supplies this assembly for fiber optic builds, telecom drops, and general outside plant construction.
