The Channell Commercial ACC06028202 (Millennium part #522622) is a handhole accessory used with Channell's ACC7734-series composite enclosures that protect fiber optic and copper cable splices at buried access points. It supports the assembly's fit and seal, helping the handhole resist moisture intrusion, soil pressure, and vehicle traffic over its service life. Designed for quick field installation, it allows crews to maintain or upgrade existing handholes without replacing the entire enclosure. Millennium keeps the ACC06028202 in stock for telecom and fiber optic construction and maintenance work.
