Aluminum Long Barrel 2 Hole Compression Lugs

Aluminum Long Barrel 2 Hole Compression Lugs are designed for high-strength, vibration-resistant electrical terminations where stability and long-term reliability are critical.

Constructed from high-conductivity seamless aluminum, these long barrel compression lugs provide extended conductor engagement for maximum surface contact and reduced electrical resistance. The long barrel design supports multiple compression points, resulting in improved mechanical strength and consistent electrical performance in demanding environments.

Two-Hole Design for Added Stability
The two-hole palm design provides enhanced mechanical stability compared to single-hole lugs, helping prevent rotation and movement after installation. This makes two-hole compression lugs especially well suited for applications involving vibration, thermal expansion, or high fault current conditions. The precision-formed palm sits flat against bus bars, grounding bars, and equipment terminals to ensure proper torque and secure contact.

Key Features and Construction
• AL9CU dual rated for aluminum and copper conductors
• Long barrel design for multiple compression points and improved conductivity
• Two mounting holes for added stability and anti-rotation performance
• High-conductivity seamless aluminum construction
• Factory-applied oxide inhibitor inside the barrel
• Barrel capped to keep conductors clean prior to installation
• Uniform electro-tin plating for corrosion resistance and reduced contact resistance
• Color coded barrels for quick wire size and die identification
• Clearly marked with wire size, stud size, and die index

Applications
Aluminum Long Barrel 2 Hole Compression Lugs are widely used in switchgear, transformers, panelboards, motor control centers, grounding systems, generators, renewable energy installations, and utility power distribution. They are ideal for feeder conductors, grounding electrode conductors, bonding jumpers, and equipment terminations where a secure, non-rotating connection is required.

These lugs are suitable for indoor and outdoor installations, including electrical rooms, mechanical rooms, industrial facilities, substations, and utility enclosures.

Sizes and Compatibility
This collection includes a broad range of wire sizes and stud configurations to accommodate both medium and large conductors. Each lug is designed for use with standard compression tools when installed using the specified die index, helping ensure consistent, code-compliant terminations.
