Hammond CBB77 44U Copper Ground Busbar, 77 in Full Length

The CBB77 is a full-length copper ground busbar designed for bonding and grounding inside Hammond C2 Series cabinets. It gives data centre, IT, AV and electrical contractors a single vertical bonding point for equipment ground conductors, shelf and panel bonding leads, and rack-mounted hardware, keeping ground paths short, organised and inspectable inside the frame.

Construction is a continuous copper strip measuring 0.63 in (16 mm) wide by 0.13 in (3 mm) thick, running the full 77.00 in (1956 mm) height of this part number. Because the strip is one uninterrupted piece rather than a series of short bars, the CBB77 covers a 44U mounting height, so ground leads can be landed near the equipment they serve anywhere up the cabinet.

Mounting hardware for attachment to the rack frame side struts is included, so the busbar installs vertically along the cabinet frame without additional brackets. The CBB Series is intended for use with the C2 Series only; confirm your cabinet frame height matches the 77 in busbar length before ordering.

The CBB77 is RoHS and REACH compliant, TAA compliant for GSA Schedule purchases, USMCA compliant and manufactured in North America, with a shipping weight of 4 lbs (1.81 kg). ECCN is EAR99 and the tariff code is 7326.90.8688.
