Hammond CBB35 20U Copper Ground Busbar for C2 Cabinets

The CBB35 is a full-length copper ground busbar from the CBB Series, designed to provide a common bonding and grounding point inside Hammond C2 Series cabinets. It suits data centre, network and industrial control installations where equipment grounds, shelves, panels and PDUs must be tied back to a single accessible bar rather than to random frame points.

The bar is a copper strip measuring 0.63" (16 mm) wide by 0.13" (3 mm) thick, with an overall height of 35.00" (889 mm) on this size. That length covers a mounting height of 20U, so the CBB35 gives grounding access alongside a substantial portion of the mounting space in the enclosure. Copper construction keeps the bonding path low in resistance across the full length of the bar.

Mounting hardware for attaching the busbar to the rack frame side struts is included, so the bar installs vertically along the strut without additional brackets. The CBB35 is specified for use with C2F1935... frames and is intended for use with the C2 Series only; it is not a universal accessory for other rack platforms.
