Opt-X® 15 inch depth for high-density fibre termination and/or splicing. Stackable and adjustable fibre rings simplify cable organization. Front saddles pivot for improved patch cord routing. Removable front and rear covers offer better access to the interior of the enclosure. Removable rubber grommet allows for pre-terminated fibre trunk install, protects cable and minimizes dust build-up. Sliding tray (an option in 1RU and 2RU enclosures) glides forward and backward for front and rear bulkhead access after installation and removes completely from enclosure for ease of field terminations and splicing. Constructed of 16-gauge steel, powder-coated black. 1RU or 2RU retrofit sliding trays, sold separately, allow for higher-density applications using HDX MTP® cassettes or HDX adapter plates (sliding tray does not accommodate splice trays).
