Blackburn FBG12-1 FLEX BRAID 9/16H .38 X 1.5 X 12 IN

The FBG12-1 has a 9/16 inch hole at each end, so it lands on a 1/2 inch bolt or stud with clearance. It is a 1-hole flat braid connector, meaning one bolt hole per terminal pad, so you need a single 1/2 inch bolt, nut and washer at each connection point. Hardware is not part of the braid itself.

Overall length is 12 inches, and the braid measures .38 x 1.5 x 12 inches. Use the 12 inch length when you need real movement or offset between the two bonding points, such as across an expansion joint or to a piece of equipment that vibrates. For tight bus-to-frame jumpers a shorter braid in the same family is the better pick.

Yes, the FBG12-1 flexible braid connector is UL and CSA Listed, which is what an inspector or a spec on an institutional job will be looking for on a bonding jumper. It is also made in the United States.

That is exactly what it is for. The FBG12-1 is a flexible flat braid rather than a solid bar or a stiff cable lug, so it absorbs vibration, thermal expansion and small misalignment between the two bonded points without stressing the bolted terminals. Typical uses are motor frames, transformer enclosures, generator skids, switchgear doors and across building expansion joints.

The FBG12-1 conductor is tin-plated copper. The tin plating is there to slow oxidation of the copper and reduce the dissimilar-metal reaction at a bolted joint, which is why tinned braid is the usual choice outdoors, in damp vaults and on aluminum or galvanized surfaces. Clean the mating surface to bright metal and apply an oxide inhibitor at the joint.

Flat braid like the FBG12-1 flexes repeatedly without work-hardening and gives more surface area in a thin profile, so it fits behind panels and in tight equipment gaps where a cable and lug assembly will not bend. Stranded cable with crimped lugs is the better answer for long runs and higher ampacity grounding electrode conductors. For a short, moving, bolt-to-bolt bond, the braid is the correct part.

It is sold each, one braid per unit, under manufacturer part number FBG12-1. Order one per bonding point you are jumping, and remember each end needs its own bolt, nut and washer since the bolting hardware does not come with the braid.
