Blackburn FBXD6 FLEX BRAID 2 9/16H .25X 1.25 X 6 IN

The pads are punched two-hole at 9/16 inch diameter, so it takes 1/2 inch hardware with clearance. Confirm your pad's hole spacing matches before you drill anything, because the hole size only settles the bolt diameter, not the centers.

It carries both UL and CSA Listing, which is what an inspector or a spec writer on a government, healthcare, or education job typically wants to see on a bonding jumper. It is also made in the United States, which matters where domestic-content rules apply.

The FBXD6 is a flat, flexible tin-plated copper braid jumper with a terminal pad at each end, drilled two-hole. It bridges two bolted connection points that need to stay electrically bonded while allowing movement or vibration between them, which is why the conductor is braid rather than solid bar. Common uses are switchgear bus bonding, transformer and enclosure grounding, and equipment that shifts or expands in service.

Use the braid wherever the two points move relative to each other: across a hinged enclosure door, between a transformer case and its frame, over an expansion joint, or on anything that vibrates. A solid bar is fine on rigid, fixed bus where nothing shifts, and it is cheaper to fabricate. Braid is a flat flexible conductor, so it absorbs that movement without work-hardening a solid strap at the bolt hole.

The conductor on the FBXD6 is tin-plated copper. The tin plating slows surface oxidation at the bolted pad, so the contact resistance stays stable over time, and it reduces galvanic issues when you are landing on aluminum or plated steel bus. Bare copper works but wants more attention to joint compound and periodic retorque.
