Mechanical Lugs or set screw lugs are typically made of aluminum or copper, and are designed for fast and reliable mains-to-mains jointing, for power and grounding applications. Electrical connectors come in many different styles and functionalities. Electricians use this type of connector for rewiring jobs, due to their reliability and durability. A cable lug is a flat-ended, crimped copper or aluminum metal used in connecting cables, such as attaching electrical appliances to a motor or terminal in heavy-duty environments. Fiber optic connectors are a quick and easy way to attach and detach two fiber optic cables, and are primarily used in the telecommunications, aerospace, and defense industries. Zoro also has a super selection of wire connectors and cable lugs too.
