Conversions Tech Split Bolt Connector – 350 MCM to 4/0 SOL Heavy-Duty Brass Splicing
The Conversions Tech Split Bolt Connector is a high-performance electrical connector engineered for secure splicing and termination of large-gauge copper conductors ranging from 350 MCM to 4/0 AWG Solid (SOL). Designed for demanding electrical environments, this connector delivers superior electrical conductivity, strong mechanical retention, and long-term corrosion resistance across industrial, commercial, and power distribution applications.
Manufactured from high-strength, high-conductivity brass (CuZn alloy), this split bolt provides consistent clamping force and excellent resistance to deformation under load. Precision-machined threads and a robust bolt design ensure reliable electrical contact even in installations subject to vibration, thermal cycling, and high current loads.
