Aluminum Long Barrel 1 Hole Compression Lugs

Aluminum Long Barrel 1 Hole Compression Lugs are designed for high-performance electrical terminations where conductivity, mechanical strength, and long-term reliability are critical.Manufactured from high-conductivity seamless aluminum, these lugs feature an extended barrel length that allows for multiple compression points. This long barrel design maximizes conductor contact, reduces electrical resistance, and improves pull-out strength, making these connectors well suited for demanding installations involving vibration, thermal cycling, and high current loads.

Key Features and Construction
• AL9CU dual rated for use with aluminum and copper conductors
• Long barrel design for enhanced conductivity and multiple compression points
• High-conductivity seamless aluminum construction
• Factory-applied oxide inhibitor inside the barrel to reduce oxidation
• Barrel capped for cleanliness and protection prior to installation
• Uniform electro-tin plating for corrosion resistance and reduced contact resistance
• Precision-formed palm with a single mounting hole for secure bolted connections
• Flat palm design for proper torque and consistent surface contact
• Color coded barrels for fast wire size and die identification
• Clearly marked with wire size, stud size, and die index

Electrical Applications
Aluminum Long Barrel 1 Hole Compression Lugs are commonly used in a wide range of electrical systems and installations, including power distribution equipment, switchgear, panelboards, transformers, motor connections, grounding bars, bus bars, generators, HVAC equipment, solar and renewable energy systems, and utility infrastructure.

These lugs are ideal for feeder conductors, grounding electrode conductors, bonding jumpers, service entrance connections, and large conductor terminations where safety and performance are essential. Their corrosion-resistant finish makes them suitable for both indoor and outdoor use in electrical rooms, mechanical rooms, industrial facilities, and utility enclosures.

Available Sizes and Compatibility
This collection includes both small AWG and large AWG aluminum long barrel compression lugs to support a wide range of conductor sizes and stud configurations. Each lug is designed to work with standard compression tools when used with the specified die index, ensuring consistent and code-compliant installations.
