Blackburn FB2D18-1 FLEXBRAID 153.6 KCMIL 18INCH 1 HOLE

The FB2D18-1 is a flat flexible braid bonding jumper, 18 inches long, with a single-hole terminal for bolting to equipment. Flexible braid is what you use where a rigid conductor won't work: bonding across an expansion joint, across a hinged or removable panel, across vibrating or moving equipment, or jumping around a nonconductive section of raceway or a water meter. The braid flexes with the movement instead of fatiguing the connection.

Yes. The FB2D18-1 is covered under UL file E3060 and CSA file LR29625, so it will satisfy an inspector or a spec calling for a listed bonding jumper on both sides of the border.

One hole per terminal pad. A single-hole braid is fine for a straight bond to a busbar, an enclosure lug pad, or a ground bus where there's only one tapped hole available. If your pad has two-hole NEMA drilling and the spec calls for a two-hole connection to prevent rotation, you need the two-hole version of the braid instead of this one.

Tin-plated copper. The tin plating is what matters outdoors, in damp vaults, or in a corrosive industrial atmosphere, since bare copper oxidizes and the resistance at the joint climbs. Plated copper is also the safer choice when you're landing on an aluminum or galvanized surface.

The cable length is given as 18 inches for the braid itself. Allow for that plus some slack when you're spanning an expansion joint: a bonding jumper should never be pulled taut, because the whole point of flexible braid is that the joint can move without loading the connection.

Country of origin is the United States, which is what a federal, state, or transit agency procurement officer needs for a Buy American or BABA line item. Pair that with the UL E3060 listing and the part clears most public-works submittals.

Stranded cable bends, but it doesn't take repeated cyclic movement the way flat braid does, and a crimped lug on a stranded jumper is a fatigue point. Flat flexible braid like the FB2D18-1 is built for the repeated motion you get at a building expansion joint, a seismic joint, or on equipment that vibrates. For a fixed bond between two things that never move relative to each other, ordinary stranded conductor with lugs is the cheaper and perfectly acceptable answer.

Each. One FB2D18-1 braid per unit, so order one per bond point. On a run of expansion joints or a row of switchgear sections, count your joints first, since each crossing needs its own jumper.
