The NSI GL1038 1-Hole Standard Copper Compression Lug features one standard installation hole, sized for 3/8” mounting bolts, and one chamfered port to terminate a 1/0 AWG conductor. These connectors are made from tin-plated copper for improved conductivity and corrosion resistance. The legible die index and pink color-coding markings make them easy to identify, while the installation process only requiring a crimp tool makes them easy to use. NSI compression lugs are built for professionals, with a reliable one-piece construction produced from high-conductivity copper tubing and a closed barrel design that protects against moisture and contaminants. Compression crimping makes a homogeneous connection between connector and conductor, forming a vibration-resistant, mechanically strong unit. Use these lugs for many applications including secondary power distribution in buildings, power plants, industrial applications or with electrical equipment.
