Opt-X® 1000i rack mount enclosure. Constructed of 16-gauge steel, powder-coated black. Plastic parts made using self-extinguishing ABS and polycarbonate materials rated UL 94 V-2. Grommet material made of Santoprene® thermoplastic rubber elastomer. 15 inch depth for high-density fiber termination and/or splicing. Stackable and adjustable fiber 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 fiber 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. Enclosure allows for inter-connect or cross-connect between backbone cable and active equipment while using minimum rack space in a frame or cabinet setting. Features and design allow for easy field termination of connectors, splicing or pre-terminated plug-n-play solutions. Used in data centres, equipment rooms and telecommunication rooms.
