What is a Split Bolt Connector?
A split bolt connector is a certified electrical fitting used for splicing, connecting, and grounding copper and aluminum conductors. Its split design and adjustable central bolt allow for easy, tool-friendly installation without special equipment, providing a reliable, corrosion-resistant connection that complies with UL 467 and CSA standards. It is widely used in power distribution, electrical construction, grounding systems, and industrial wiring projects.
