4 AWG Two-Hole Long-Barrel Copper Compression Lug – 3/8″ Stud, 1″ Spacing
Conversions Tech’s tin-plated copper two-hole compression lug delivers rock-solid, low-resistance terminations for 4 AWG conductors. Dual 3/8″ studs with a standardized 1″ spacing lock firmly onto busbars, disconnects, or grounding plates, while the extended barrel maximizes crimp contact for superior vibration resistance in industrial, commercial, and residential power systems.
Key Benefits
- 4 AWG Conductor Fit — engineered for secure, code-compliant 4 AWG terminations.
- Dual 3/8″ Studs (1″ OC) — standardized spacing ensures rock-steady, torque-balanced mounting.
- Long-Barrel Design — increased crimp surface area for maximum conductivity and vibration immunity.
- Tin-Plated 99.9 % Copper — fights corrosion while maintaining ultra-low resistance.
- 125 A / 35 kV Rated — handles demanding loads up to 90 °C.
- UL Recognized, CE & RoHS Compliant — meets global safety and environmental standards.
