Leviton – OPT‑X 1000i SDX Rack‑Mount Enclosures (1RU, 2RU, 3RU, 4RU) — 5RxUM‑xxx

OPT‑X 1000i SDX Rack‑Mount Enclosures provide compact, high‑density fiber termination, splicing, and cross‑connect capability for data centers, equipment rooms, and telecommunications rooms. Available in 1RU, 2RU, 3RU and 4RU sizes, enclosures accept SC, LC, ST, and MTP adapters plus Plug‑n‑Play MTP cassettes and SDX adapter plates. Optional sliding trays (1RU/2RU) permit front and rear bulkhead access and ease field termination and splicing. Cable management includes stackable quarter/half/full rear rings, pivoting front saddles, removable grommet for pre‑terminated trunks, and accessory kits with ties, mounting screws, ID labels and spiral wrap. Enclosures mount in 19‑ or 23‑inch racks or cabinets and offer optional locking door hardware.
