Harrington Industrial Plastics (Harrington) is pleased to announce the acquisition of Commercial Industrial Supply (CIS), in partnership with CIS’s owner, Ron Heisler. Commercial Industrial Supply, based in Rock Hill, SC, is a leading distributor of thermoplastic fittings, valves, pipe, consumable filtration, and other products and key suppliers that align closely with Harrington. CIS was co-founded in 2009 by Ron Heisler. Ron began his career in contracting early on and understood the needs and challenges of the industry. His goal was to provide local contractors and other professionals with the highest quality products on the market. Today, CIS is doing just that and more. Ron and his team have built CIS into a highly respected company with a loyal customer base, differentiated inventory breadth and depth, and industry-leading same-day fulfilment. CIS has developed a particularly strong position in the online sales channel that has allowed the company to tap an underserved segment of the industry and consistently outgrow the overall market. The acquisition will help accelerate Harrington’s own e-commerce and online lead generation capabilities. CIS serves heavy industrial contractors, individual contractors, OEMs, and end users such as the military, industrial plants, labs, and universities.
