CLC8T48BK is a black textured steel top panel for the Hammond CLC Series multi-bay colocation server rack cabinet, specified for use with frames of 48.00 in (1219 mm) depth. It is intended for data center, colocation and telecom teams who need organized overhead cable entry into a shared multi-tenant cabinet while keeping the top of the frame closed off.

The panel is built from mild steel with a black textured powder coat finish. Per the drawing, the assembly consists of one colocation top panel, four 3-inch brush gasket trims and four two-hole brush gasket clamps; the drawing notes that mounting hardware and brush gasket are included. Eight brushed cable entries let power and data cabling pass through while limiting open airflow paths, and six 0.375 in diameter knock-outs are provided for additional routing or accessory attachment.

Overall panel dimensions on the drawing are 45.25 in (1149 mm) by 21.75 in (552 mm). The manufacturer's long description for CLC8T48BK identifies it as the 48D top panel with 8 x brushed entry and rear opening, while the series ordering table lists CLC8T48BK in the "8x Brushed Entry with Center Opening" top panel column. The series data states that the top panel opening fits any C2T1923 C2 top panel or CLCH chimney, so the panel can be used as a base for chimney or containment build-ups.

CLC cabinet assemblies ship without a top panel, so a panel such as CLC8T48BK is selected to match the frame depth. The part carries UL file E474597 and the series standards listing of cULus, PCI and TAA-compliant, and it is RoHS and REACH compliant, USMCA compliant and made in Canada.
