Build dense fiber terminations without sacrificing access or protection. Black Box designed this rack-mount cabinet for 19 in and 23 in rack applications where flexibility and connection density matter. It accepts up to six adapter panels or LGX cassettes, giving infrastructure teams a modular way to scale terminations as requirements change. The lockable Plexiglas front door helps shield patch cords from dust and dirt while still allowing visual inspection of connections. That matters in active network spaces where technicians need quick confirmation without exposing the terminations to unnecessary handling. Cable management is included to help maintain bend-radius discipline and keep the front of the rack orderly. At 3.5 in high and 13.8 in deep, this cabinet fits neatly into structured fiber deployments where space efficiency and serviceability must coexist. RoHS compliance, a Taiwan country of origin, and a lifetime warranty make it a strong fit for procurement teams that value long-term support and documented infrastructure quality.
