Blackburn FBE1H050A3-12 1H JMPR BRD ASY2 500 H7/16x2 L12

The FBE1H050A3-12 braid measures 12 inches (304.8 mm) overall, which is the length you need to check against the span between your two bonding points. Flexible braid is meant to be installed with a little slack so it can absorb movement, so measure the actual path rather than the straight-line gap before committing to this length.

The terminals are punched with 7/16 inch holes, so a 3/8 inch bolt or stud passes through with clearance. Confirm the tapped hole or stud already on your enclosure, busbar or frame matches before you order, because an oversized hole cannot be reduced in the field without a shim washer.

No. It is a non-insulated braid, so the conductor is bare along its full length. That is normal for grounding and bonding jumpers, but it means you have to keep the run clear of live parts and of any surface where bare copper contact would be a problem.

It is an extra-flexible jumper braid, a grounding and bonding device used to bond two points that move or vibrate relative to each other, such as across an expansion joint, a hinged enclosure door, transformer or motor frames, or equipment on vibration isolators. The braided construction flexes where a solid or stranded conductor would work-harden and break.

It ships as an assembly, not cut braid stock, described as a 12 inch jumper braid assembly with a 7/16 inch hole terminal pattern at two places. You still supply the bolts, nuts and washers for landing it, and any antioxidant compound your spec calls for.

The braid is built to NEMA and is manufactured in the United States. Those are the two items most often requested on institutional and government submittals, alongside the manufacturer part number FBE1H050A3-12.

Sold each, so one order quantity equals one 12 inch braid assembly. For a run of enclosure doors or a bank of isolated equipment, order one per bonding point rather than expecting a multi-pack.
