Blackburn FBF36 FLEX BRAIDS 36INCHES LONG

The FBF36 is a flat flexible copper braid connector used to bond two points that move or vibrate relative to each other, such as a transformer case to a ground bus, equipment frames, hinged enclosure doors, or bus bar to bus bar. The braid construction lets the connection flex without work-hardening a solid conductor, while still carrying fault and bonding current through copper.

It is a 1-hole flexible braid connector, so each end lands on a single bolt or stud. One fastener per termination point, sized to the hole. That makes it quick to install on a drilled ground pad or bus, but it does not resist rotation the way a 2-hole lug does, so it is not the part to use where a two-hole NEMA bolt pattern is specified.

The FBF36 carries CSA/UL certification, so it can be used on work inspected to either the NEC or the Canadian Electrical Code without a field evaluation on the connector itself. It is also made in the United States, which matters on Buy American and federal or municipal procurement jobs.

Use the braid wherever the two ends move: equipment on vibration isolators, hinged panel doors, rail or crane connections, expansion joints in bus. A stranded cable jumper is fine for static bonds and is easier to route in conduit, but repeated flexing fatigues it. The FBF36 is flat and flexible by construction, so it takes the motion and still lies tight against a flat pad instead of standing off it.

The braid is supplied as the conductor with its terminations only. Bolts, nuts, flat and lock washers, and any antioxidant compound for the mating surface come from your own stock, sized to the pad or stud you are landing on. Clean the contact surface before you torque it down; a bonding path is only as good as the metal-to-metal contact at each 1-hole termination.

Sold each. One 36 inch braid per unit, so order one per bonding point and remember most jobs need a pair of terminations planned, not a pair of braids.
