Product OverviewThe Middle Atlantic BB-12 is a 12-space solid copper bus bar that slips directly into a rack chassis to serve as an electrical conduit for large circuits. The bar m easures 1/8 inch thick, 2 inches wide, and 21 inches high, with 10-32 threaded connection points along its length. All required mounting hardware is included. High-purity copper construction delivers the conductivity that grounding and power bonding applications demand.Product DescriptionReliable equipment grounding starts with a low-impedance path, and solid copper remains the benchmark conductor for that job. The BB-12 gives integrators a 12 RU vertical copper bus bar that installs directly into a Middle Atlantic rack chassis, creating a common connection point for ground wires and large-circuit bonding within the enclosure. The bar is a substantial piece of metal: 1/8 inch thick and 2 inches wide across its 21-inch height, with 10-32 threaded points that accept ring lugs and bonding hardware without separate nuts. Middle Atlantic uses high-quality copper because conductor purity makes a measurable difference in electrical conduction, and the threaded strip forms a dependable backbone for rack power and grounding schemes. Everything needed for installation comes in the box, so there is no hunting for compatible fasteners on site. For taller grounding runs, the same family includes 40 and 44-space versions, but the BB-12 is the right size for compact racks, credenza enclosures, and equipment clusters where a full-height bar is unnecessary. It is a simple component that quietly underpins clean audio, stable video, and safe electrical practice in any professionally built rack.Key Features Solid Copper Construction — High-purity copper for the low-impedance conduction grounding applications require. 12-Space Height — 21-inch bar sized for compact racks; covers a 12 RU section of the rack frame.
