CLC6T48BK is a replacement or configuration top panel for Hammond CLC Series colocation server rack cabinets built on the 48.00 in (1219 mm) deep frame. CLC cabinet assemblies ship without a top panel, so data center, colocation and telecom teams select the panel that matches their cable routing and thermal strategy. This version combines brushed cable entries with a rear opening, making it suited to installations that need both organized overhead cable pass-through and a path for exhaust containment.

The drawing identifies the part as a CLTOP chimney panel with 6 holes and brush gasket, painted black textured to match CLC cabinets. It is fabricated from mild steel and measures 45.25 in (1149 mm) by 23.75 in (603 mm) overall, with a 21.75 in (552 mm) by 19.06 in (484 mm) opening area and six 0.375 in knock-outs. The assembly includes one colocation top panel, two 3 in brush gasket trims and two 3-hole brush gasket clamps; mounting hardware and brush gasket are included per the drawing notes.

Per the series ordering table, the top panel opening accepts any C2T1923 C2 top panel or CLCH chimney, so CLC6T48BK can act as the transition between the cabinet and a chimney or containment component rather than a fixed solid lid. The brushed entries help keep cable openings closed around bundles while cables are routed to overhead trays, adjacent cabinets or vertical PDUs inside the cabinet bays.

CLC6T48BK carries UL file E474597 and is listed under cULus, PCI and TAA-compliant standards, is RoHS and REACH compliant, USMCA compliant and manufactured in Canada for procurement programs that require North American sourcing.
