The braid measures 19.5 inches (495.3 mm) overall, so plan the bond path with that length in mind. On a busbar-to-enclosure or fence-post bond it gives enough slack to route around a corner without putting tension on the terminal pads. If your span is much shorter, coil or dress the excess rather than cutting it, since the terminals are factory attached at both ends.

The model designation calls out 9/16 and 7/16 terminal holes, one at each end. Confirm the drilling on your busbar or ground pad matches: a 7/16 hole takes a 3/8 inch bolt and a 9/16 hole takes a 1/2 inch bolt with normal clearance, so you can bolt one end to a 1/2 inch stud and the other to a 3/8 inch stud without drilling or adapters.

It is a bare braid, not jacketed. The insulation material field reads N, meaning no insulation. That is normal for a flexible ground braid used across expansion joints, on switchgear doors, or between a grounding busbar and a frame, but it also means it must not be routed where it can contact energized parts or chafe against a live terminal.

Country of origin is the United States, and the braid is built to NEMA. That combination is what most government, utility, and institutional specs are looking for when domestic sourcing language appears on the drawing.

A braid is the right choice anywhere the two bonded parts move relative to each other, hinged equipment doors, expansion joints, vibrating machinery frames, or seismic gaps, because the flat braid flexes repeatedly without work hardening and breaking the way solid or stranded conductor can. Where both ends are rigidly fixed and nothing moves, ordinary bonding conductor and lugs will do the job. This Blackburn part is a flexible jumper braid with terminals already fitted at 19.5 inches, so it is a drop-in for the moving-joint case with no lug crimping on site.

Selling unit is each, so one quantity equals one complete jumper braid with both terminals attached. For a switchgear or substation job where you need a bond at every hinged door or expansion joint, order one per connection point rather than expecting a multi-pack.
