Cerrowire has a rich history that dates back to the 1920s, when it was initially established as Circle Flexible Conduit Co., Inc. The company began by manufacturing armored cable and flexible steel conduit. Over the decades, Cerrowire expanded its offerings and operations significantly, evolving into a key player in the copper wire industry. In 2009, it rebranded from Cerro Wire & Cable to Cerrowire and has since been recognized for its innovative products such as CerroMax™ and ReelRover wire handling devices, which enhance installation efficiency and safety.

Today, Cerrowire stands out for providing high-quality copper and aluminum wire solutions tailored for various applications including residential, commercial, and industrial sectors. Their product range features MC cables, building wires, portable cords, specialty wires, and value-added packaging services. Cerrowire maintains state-of-the-art manufacturing facilities across multiple states including Alabama, Georgia, Indiana, and Utah. As a part of Berkshire Hathaway's Marmon Group since 2008, Cerrowire continues its legacy of innovation while focusing on customer satisfaction through timely delivery and superior service.
