This 6-pack of 2-port inline splice connectors offers a versatile solution for secure and efficient wire connections. The kit includes 3 different types of aluminum-copper connectors, totaling 6 insulated multi-connectors, suitable for a wide range of applications. Designed for compatibility with 250 MCM, 3/0 AWG, 2/0 AWG, 1-1/0 AWG, 2 AWG, 4 AWG, 6 AWG, 8 AWG, 10 AWG, 12 AWG, and 14 AWG wires, these connectors provide multiple usage options in a single set. Each connector features dual-entry ports and slotted Allen hex screws, allowing easy installation and strong, secure connections. The pre-filled lubricating oil in the ports contains antioxidant properties, protecting the connection against corrosion and extending its lifespan. The insulated design enhances safety and reliability, using high dielectric strength plastic sol that resists chemicals and wear. These connectors are more convenient than butterfly nut connectors, offering a larger wire diameter range and higher current capacity. Ideal for both residential and industrial electrical projects, they simplify cable management while ensuring consistent performance. Easy to remove and re-insert cables as needed, these connectors are a practical and dependable choice for professionals and DIY users alike.
