A mechanical lug is a heavy-duty lug often used in electrical and construction applications. It’s designed to accommodate a wide range of connectors. Also referred to as “electrical lugs,” mechanical lugs are used for larger wires and cables. They’re often constructed from aluminium or copper.

The SAL Series of mechanical lugs carried by Greaves are available in a wide range of sizes and fashioned from high-strength extruded aluminium alloy. They’re also electro-tin plated and come with slotted screws for easy installation.
