SystemShield #10–14 AWG Two-Hole Copper Compression Lug — 3/8" Hole — 1" Spacing

#10–14 Two-Hole Long Barrel Copper Compression Lug — 3/8 in Holes — 1 in Spacing

Short Description

Two-hole long barrel copper compression lug for #10–14 AWG copper conductors, built with 3/8 in mounting holes, 1 in hole spacing, and an inspection window for grounded, repeatable bonding and grounding terminations.

Product Overview

The SystemShield #10–14 Two-Hole Long Barrel Copper Compression Lug is a grounding and bonding termination component used to create a secure compression connection between smaller copper conductors and a bolted grounding or bonding point.

This lug is designed for #10–14 AWG copper conductors and uses a two-hole long barrel format that improves terminal stability versus single-hole styles in many grounding and bonding applications. The 3/8 in hole size and 1 in center-to-center hole spacing align with common grounding bar and bonding terminal patterns used across equipment frames, enclosures, telecom backboards, and grounding bars.

Its long barrel configuration supports compression-style conductor termination, while the inspection window provides visual confirmation of conductor insertion before crimping. This lug is well suited for structured grounding layouts where stable two-bolt mounting and repeatable conductor termination are required.

Key Features

• Designed for #10–14 AWG copper conductors
• Two-hole long barrel format for more stable bolted attachment
• 3/8 in hole size for common grounding and bonding termination points
• 1 in hole spacing for standard two-hole mounting patterns
• Copper construction for conductivity and grounding use
• Tin-plated finish for corrosion resistance and termination reliability
• Inspection window for conductor insertion verification
• Suitable for grounding bars, equipment bonding points, chassis, and enclosure terminations

Not intended as:

• A mechanical set-screw connector
• A single-hole lug substitute where two-hole mounting is required
• A finished assembly by itself without conductor and proper crimp installation

Installation Notes

Use this lug only with a compatible #10–14 AWG copper conductor and the correct compression tooling and die profile appropriate to the lug manufacturer’s crimp system.

Before crimping, verify full conductor insertion through the inspection window and confirm that the target bonding or grounding point matches the 3/8 in hole size and 1 in spacing.

Installer should verify:

• correct conductor size
• correct crimp die and tool compatibility
• full conductor insertion
• mounting-hole pattern match
• applicable code and equipment requirements before installation

Compliance & Regulatory Information

Components used in this product may be UL listed or UL recognized where applicable.

This lug should be used only as part of a properly designed grounding or bonding system and installed in accordance with applicable NEC requirements, connector manufacturer instructions, equipment manufacturer instructions, and project grounding specifications.

Packaging & Handling

• Protect against surface contamination
• Protect against barrel deformation
• Protect against mounting palm damage
• Protect against corrosion from improper storage conditions

Store in a clean, dry environment before use. Do not use damaged or deformed lugs for grounding or bonding terminations.

Notes / Limitations

This product is a termination component, not a complete grounding assembly.

• Final suitability depends on correct conductor sizing
• Correct crimp tooling and die selection are required
• Correct mounting geometry is required
• Proper installation practices are required
• Overall grounding system design remains application-dependent
