Flex Lugs

Shop flex lugs for terminating flexible, fine-stranded and high-strand-count copper conductors in electrical, grounding, power distribution and telecommunications applications. Flex cable lugs provide a compression connection between a conductor and a compatible bus bar, ground bar, terminal pad or equipment connection point. They are used where flexible cable requires a lug barrel designed for its conductor construction.

This collection features copper compression flex lugs in one-hole and two-hole configurations. Available styles include straight, 45-degree and 90-degree tongues, along with standard, narrow-tongue, long-barrel, bell-end, inspection-window and no-window designs. Multiple conductor ranges, stud-hole sizes and hole-spacing options help installers match the lug to the cable and mounting surface.

Flex lugs are commonly used with flexible copper cable, welding cable, diesel locomotive cable, battery cable and other high-strand-count conductors. Applications include telecom grounding and bonding, battery systems, power equipment, electrical cabinets, equipment racks, ground bars, bus bars, generators and industrial power connections. Angled flex lugs can help align conductors with connection points when the cable cannot approach the mounting surface in a straight path.

Selecting the correct flex cable lug requires matching the lug to the conductor material, cable size and strand class. The tongue configuration must also coordinate with the number of mounting studs, stud diameter and hole spacing on the equipment or grounding component. Barrel length, tongue width, orientation and the presence of an inspection window are additional factors that can affect fit within an enclosure or equipment assembly.

Flex lugs are installed using compatible compression tooling and dies specified for the lug and conductor combination. A properly matched crimping system creates the intended mechanical connection between the cable and lug barrel. Installers should identify the required conductor preparation, die reference and compression sequence for the selected component and application.
