​Brand: Unbranded / Industrial OEM

​Type: Flexible Busbar / Grounding Strap / Shunt

​Material: Multi-Layer Braided Copper Wire with Tinned/Plated Copper Terminal Ends

​Quantity: Lot of 6 Shunts (3x 4-Layer, 3x 3-Layer)

​Overall Length: 6.0" (4-Layer) and 6.25" (3-Layer)

​Terminal Width: 1.5 Inches (1-1/2")

​Terminal Hole Diameter: 1/4 Inch

​Hole Spacing: 3/4 Inch Center-to-Center



​Up for sale is a lot of (6) heavy-duty multi-layer braided copper flexible shunts. Features 1.5" wide tinned terminal pads with dual 1/4" mounting holes spaced 3/4" center-to-center. Designed to carry massive electrical current while absorbing continuous vibration and thermal expansion.

​Lot Breakdown & Dimensions:

​(3) 4-Layer Shunts: 6.0" Overall Length – Maximum thickness for ultra-high amperage capacity.

​(3) 3-Layer Shunts: 6.25" Overall Length – Slightly longer with added mechanical flexibility.

​Multi-Use Industrial & Custom Applications:

​Solar & DIY Battery Racks: Excellent flex-bridges for large prismatic lithium battery banks, power wall setups, or off-grid inverter links.

​Automotive & Marine Upgrades: Heavy-duty "Big 3" engine-to-frame grounding straps, high-draw winch connections, or 3000W+ custom car audio grounds.

​Industrial Maintenance: Ideal replacement shunts for resistance spot welders, transformer secondary leads, induction heating equipment, or generator switchgear.

​Custom Busbars: Can be stacked in parallel to double ampacity or bolted end-to-end to create longer custom jumper runs.


​Harvested from never-used, new-old-stock (NOS) rail transit equipment—specifically the third-rail traction power collector shoe assembly and intake line feed for a passenger rail car.

​Because these components came from uninstalled, surplus transit assemblies, the copper braid and terminal pads have zero operational electrical wear, heat discoloration, or carbon pitting, offering pristine structural and mechanical integrity.


​Condition: Never used: Good structural condition with clean copper weave and solid crimped terminal pads. Removed from surplus commercial equipment. See photos for exact dimensions and condition details. Fast shipping, securely packaged


Note on Lot Composition: This lot includes (3) 4-layer shunts for maximum high-amperage current capacity and (3) 3-layer shunts offering added mechanical flexibility. All 6 units share the exact same 6.5" total length and 1.5" x 1/4" terminal pad dimensions."
