Machining Industrial Quality Copper

Lugs, Adapters, and Connectors

Machining industrial grade copper since 1992, American Power Connection Systems has the knowledge to machine almost any lug, adapter, and connector.

Specializing in the machining of copper lugs, copper adapters, and copper connectors, American Power Connection Systems understands the demands of the electrical market. Using only industrial grade copper, we have a commitment to superior quality and customer satisfaction.
We use copper because of its dexterity, ductility, and malleability properties. Using our machining capabilities, we create machined copper lugs, adapters, and connectors to bridge electrical circuits, no matter the shape required.
