Blackburn FBS4H235A1-24 FLEX BRAID 4 9/16H 1/2 X 3 X 24 IN

The braid is 24 inches long overall, and that length is what determines how much movement or offset it can absorb between the two bolted pads. If your equipment spacing needs a shorter or longer jumper, you need a different length in the FBS series rather than cutting this one, since the pads are factory-formed on each end.

It is a 4-hole pad connector, so each end bolts down with a four-bolt NEMA-style pattern rather than a single stud. Four-hole pads are what high-current switchgear and transformer terminals usually require, so confirm your equipment pad is drilled 4-hole before ordering; a 2-hole terminal needs a 2-hole braid instead.

It's a flexible flat braid connector used to make a current-carrying connection between two pieces of equipment that move, vibrate, or expand relative to each other, such as switchgear, bus bars, transformer terminals, and disconnect switches. The conductor is tin-plated copper in a flat, flexible braid form, and it terminates in a 4-hole pad on each end for bolted connections.

A rigid bar transmits every bit of vibration and thermal expansion straight into the terminal, which loosens bolted joints and cracks porcelain over time. The flat braid conductor flexes instead, so it carries current across a joint that moves, on breaker trucks, isolators, transformer bushings, and expansion points in a bus run. Where nothing moves, a solid bar or a rigid connector is the simpler choice.

The conductor is tin-plated copper. The tin plating protects the copper strands against oxidation and corrosion in outdoor and humid substation environments, and it is the plating normally specified where a copper braid lands against aluminum bus so the joint resists galvanic attack. Standard joint compound and proper bolt torque still apply at the pads.

It is sold each, one braid per unit, with the terminal pads already formed on both ends. If you are jumpering multiple phases, order one per phase.
