This 6-piece set of 2-port insulated multi-connectors is designed for secure, efficient cable connections across a wide wire range, including 2/0, 1-1/0, 2, 4, 6, 8, 10, 12, and 14 AWG. Each connector uses slotted Allen hex screws to hold wires firmly in place, ensuring strong electrical contact without slippage. Pre-lubricated ports with antioxidant oil reduce corrosion and enhance conductivity. Made from high-quality aluminum with durable plastic sol insulation, these connectors offer excellent resistance to chemicals, wear, and environmental factors. Ideal for both copper and aluminum wires, they ensure safe transitions between materials and help prevent overheating and electrical fires caused by conductor mismatch. The design makes it easy to insert and remove cables, offering greater convenience compared to butterfly nut connectors. Supporting a wide diameter range and higher current, these connectors are suitable for residential, automotive, and industrial applications. The package includes 6 connectors, with 4 of each type, providing flexibility for various wiring tasks while maintaining safety and efficiency.
