The CLC2B42BK is a two-bay colocation server rack cabinet that divides a single 24 in wide, 42 in deep footprint into two independently accessible equipment compartments of 21U each. It is built for colocation data centers, managed hosting and service provider facilities, meet-me rooms and shared enterprise environments where multiple tenants or departments need separate, controlled access to their own equipment while sharing cabinet-level power and cabling infrastructure.

Construction is a 14-gauge welded steel frame with 12-gauge reinforced corner brackets and 16-gauge doors and panels, finished in RAL9005 black powder coat (GREENGUARD, TSCA and RoHS compliant). The cabinet is a UL2416 listed rack with a 3,000 lb (1,360 kg) load rating under UL file E474597, and the series is seismic tested to a 1,200 lb dynamic equipment load for applicable IBC, CBC, NBCC and ASCE requirements when anchored with the C4K-Z4 bolt-down kit.

Overall dimensions are 83.02 in x 24 in x 42 in (2,109 mm x 610 mm x 1,067 mm), with 40.13 in (1,019 mm) of usable mounting depth and 37.88 in (962 mm) of mounting height per bay. Each bay is fitted with two pairs of adjustable-depth, EIA-compliant square-hole mounting rails (12-gauge steel) with 10-32 cage nuts for standard 19 in equipment; mounting hardware is not included.

Each compartment has flush-mounted perforated vented doors with combination lock handles at 63% airflow, and a fixed divider shelf with cutout cover plates separates the bays. Removable rear panels create space for vertical PDUs and cable routing, side cable pass-through knockouts and top panel options support organized routing, and the top opening accepts any C2T1923 C2 top panel or CLCH chimney. CLC2B42BK ships without a top panel; CLCSP42BK is the matching single solid side panel.
