Sumitomo DE20IDU NEMA-1 Enclosure TDU

Deliver secure, space-efficient fiber tube management at transition and branching points with the Sumitomo DE20IDU NEMA-1 Enclosure TDU. Designed as a wall-mounted Tube Distribution Unit (TDU), this enclosure streamlines tube-to-tube connections with push-fit connectors and keeps pathways organized between network hubs, workstations, surveillance cameras and other monitoring endpoints. Its compact 20" x 20" x 7" footprint minimizes wall space usage while supporting top, bottom or side cable entry for tubes up to 2" in diameter, reducing installation time and field labor. For high-density or expanding deployments, the unit accepts the DE06MDU modular attachment—allowing a Fiber Termination Unit to mount on the door hinge—and offers perforated back panel kits for tidy tube routing and easier serviceability. Built for networking and security environments, the DE20IDU improves reliability for fiber-based security, surveillance and monitoring systems while simplifying maintenance and future upgrades. Specify the Sumitomo DE20IDU for your next enterprise, campus or security installation to accelerate deployment and protect critical fiber infrastructure.
