Blackburn FB2XD12 FLEXIBLE BRAID, 12INCHES TWO-HOLE

The FB2XD12 is a flat, flexible tin-plated copper braid connector with a two-hole terminal pad at each end. It's used to bond or ground equipment where the connection has to tolerate movement, vibration or thermal expansion, such as across switchgear doors, transformer cases, busbar joints, generator skids and equipment that shifts in service. Because the conductor is braid rather than solid bar or rigid cable, it flexes without loading the terminations.

It is both UL and CSA Listed, so it can be specified on projects in the US and Canada that call for listed bonding jumpers. Institutional and utility specs frequently require listed components for grounding and bonding, and this braid carries both marks.

The braid terminates in two-hole pads, which is the configuration NEMA two-hole ground bars, busbars and equipment bonding pads are drilled for. Two-hole terminations resist rotation under torque, which is why most commercial and utility grounding specs call for them over single-hole lugs. Check your bar's hole spacing and bolt diameter against the pad before you order, and plan on supplying your own bolts, washers and antioxidant compound.

The FB2XD12 conductor is tin-plated copper. The plating slows oxidation on the strands and at the terminal pads, which matters in damp, outdoor, marine or chemically aggressive locations and where the braid lands on aluminum or galvanized surfaces. Bare copper braid works fine indoors but discolors and builds resistance at the contact face over time in wet service.

Use flexible braid like the FB2XD12 where the two bonding points move relative to each other: hinged enclosure doors, vibrating machinery, generator and transformer connections, expansion joints in busway. Use a standard stranded cable jumper with compression lugs where both ends are fixed, since it's cheaper per foot and easier to route in longer runs. Flat braid also fits tight clearances behind panels better than round cable of equivalent cross section.

Country of origin is the United States, which matters on federal, military and utility work carrying Buy American or BAA provisions. Confirm the specific clause your contract cites, since domestic-content thresholds vary by program.

It's sold each, one braid per unit, under manufacturer part number FB2XD12. If you're bonding a row of enclosure doors or a series of busway joints, count the connections and order that quantity.
