Blackburn FBB12-1 FLEXIBLE BRAID 24 KCMIL,12inchLONG

The FBB12-1 is a flexible tin-plated copper braid bonding jumper, 24 KCMIL and 12 inches long, with a one-hole terminal at each end. It bonds two points that need an electrical connection but also need to move or vibrate relative to each other, such as across an expansion joint, a hinged enclosure door, a transformer or motor mount, or a section of equipment that gets pulled for service. The flat braid construction flexes where a solid or stranded conductor would work-harden and break.

Yes. The FBB12-1 carries UL file E3060 and CSA file LR29625, so it will pass inspection on both sides of the border. That matters on grounding and bonding work where the AHJ wants a listed jumper rather than a shop-made strap.

Cable length is 12 inches. Measure hole center to hole center on your two landing points and leave slack: a bonding braid needs a gentle bow so the movement it is absorbing is taken up by the loop, not pulled straight through the terminals. If your span is close to 12 inches with no room for slack, step up to a longer braid in the same family rather than stretching this one.

It is a one-hole flexible braid connector, so each terminal pad lands on a single bolt or stud. One-hole terminations are fine for bonding jumpers, but on a pad that sees torque or vibration a two-hole connector resists rotation better, so use a two-hole style where the equipment pad is drilled for it.

Not where the connection moves. Standard building wire is not built for repeated flexing and will fatigue at the lug. The FBB12-1 uses a flat, flexible braided conductor specifically so it can take continual motion or vibration. For a fixed, non-moving bond, an ordinary sized copper conductor and a mechanical lug is the cheaper and correct answer; save the braid for joints that flex.

The manufacturer part number is FBB12-1, from Blackburn. That single number covers the 24 KCMIL, 12 inch one-hole flexible braid; there are no finish or size options to specify on it.

The FBB12-1 conductor is tin-plated copper. The plating slows oxidation on the strand surface, which keeps contact resistance down over time and makes the braid more tolerant of damp or corrosive locations than bare copper. It also plays nicer with aluminum and plated hardware at the bolted terminal.

Sold each. Order one per bonding point, and remember a hinged door or a pair of expansion joint sections often needs a jumper on each side of the assembly.

Country of origin is listed as United States and Canada. That is the detail public and institutional buyers working under domestic-sourcing requirements usually need on the submittal.
