Blackburn FB-1241036-1 24X10/36TC FLAT BRAID 1/4WIDE

The FB-1241036-1 flat braid is sold by the foot, so you order the running length you need rather than a pre-made jumper. Order the total footage per run and cut to suit on site.

The conductor is tin-plated copper in a flat, flexible braid. The tin plating is what buys you corrosion resistance at the surface, which is why braid like this gets used for bonding jumpers in switchgear, transformer cabinets and other spots where bare copper would tarnish. It meets ASTM-B33, the standard covering tin-coated soft copper wire for electrical purposes.

Flat braid is picked over round cable when the connection has to flex or move. It is a flexible conductor in a flat profile, so it bends repeatedly without work-hardening a solid lug-to-lug run, and the flat shape lies tight against a surface or squeezes into a shallow gap behind a panel or under a cover plate. Typical uses are bonding across a hinged door, a vibrating motor frame, or an expansion joint. For a fixed, static ground run where nothing moves, ordinary stranded grounding conductor is the simpler buy.

What you are buying is the flat braid conductor itself, sold by the foot. Plan on ordering your terminations separately and sizing the lug or one-hole terminal to the braid width and to the bolt size in your bonding point.

Country of origin on the FB-1241036-1 flat braid is the United States, which is the answer most government, utility and institutional buyers need for a domestic-content line item on the submittal.

ASTM-B33 is the standard called out for the FB-1241036-1 braid, the specification for tin-coated soft or annealed copper wire used as an electrical conductor. Cite that together with the tin-plated copper conductor material when you submit it.
