Millennium part #601923, the Channell Commercial ACC7734GY-654 handhole assembly, delivers a gray composite enclosure sized to protect fiber optic or copper splice points, slack cable, and connectors below grade. Its molded logo cover simplifies identification for locate crews while the traffic-rated body withstands vehicle loading, soil pressure, and long-term moisture exposure common in roadway and easement installations. Non-conductive composite construction eliminates corrosion concerns associated with metal handholes. Millennium keeps this assembly in stock to support fiber optic network expansion, drop cable access, and OSP maintenance projects.
