Blackburn FB2D12-1 FLEX.BRAID 153.6KCMIL,12 INL,1 HOLE

12 inches of braid length, which is the dimension the part number's "12" refers to. Measure your point-to-point span plus the slack you need for movement before committing, since the braid is a fixed length and cannot be cut down without losing the factory-formed bolt pad at each end.

It carries UL file E3060 and CSA LR29625, so it is acceptable on both US and Canadian installations where an inspector wants a listed bonding jumper rather than a field-fabricated one. That listing pair is what an institutional or utility spec usually calls for.

Yes. It is a 1-hole configuration, so each end lands on a single bolt. For high-current bus work where the spec requires two-hole NEMA pad spacing to resist rotation and spread the contact area, a 1-hole braid will not satisfy that call-out and you need a two-hole version instead.

The FB2D12-1 is a flat, flexible tin-plated copper braid connector with a single bolt hole at each termination, used as a bonding or grounding jumper where two points have to stay electrically connected but need some movement or vibration isolation between them, such as across a transformer pad, a switchgear door, a bus joint, or a generator frame. The flat braid construction flexes without fatiguing the way a solid conductor would.

The braid is a 153.6 KCMIL cross section. If your drawing calls out a specific KCMIL equivalent for the bonding jumper, match that number rather than assuming a braid sized by physical width, because braid width and KCMIL do not track each other the way round conductor diameters do.

Country of origin is listed as United States and Canada. On a federally funded or utility job that requires domestic manufacture, confirm the origin marking on the carton you receive matches the clause you are working to, since the part is produced in both countries.

The tin plating on the FB2D12-1 slows oxidation on the braid strands and at the bolted pad, which matters in damp, outdoor, or corrosive environments and where the jumper bolts to a dissimilar metal. Bare copper braid will darken and build resistance at the contact faces over time in those conditions.

Sold each, one braid per unit, so order one per connection point. Bonding jobs usually take them in pairs or sets, so count your terminations rather than your enclosures.
