Carlisle Hardcast LLC (Hardcast), a wholly owned subsidiary of Carlisle Construction Materials LLC, has acquired the assets of Gripnail Corporation (Gripnail), creators of the original HVAC mechanical insulation fastener and application equipment, based in East Providence, Rhode Island. 

Gripnail manufactures fastening solutions for the HVAC industry, specifically, mechanical and weld pin fasteners as well as equipment that attaches duct liner to sheet metal air ducts. In addition, Gripnail manufactures metal tacks to fasten light loads such as name tags and wiring harnesses to pumps, valves and other types of machinery. The business acquired from Gripnail will become part of Carlisle Hardcast, within the Carlisle Construction Materials (CCM) segment of Carlisle Companies Incorporated. 

Hardcast, based in Wylie, Texas, is comprised of Hardcast Duct Sealants and Insulation Adhesives, DynAir Duct Hardware and Accessories, and the Nexus 4-Bolt Flange Closure System. As industry leaders in solutions for the HVAC air distribution system, both companies represent a combined 107 years of experience and focus on manufacturing excellence in the United States and Canada.   

Chris Ryding, CEO of Gripnail Corporation says, “Becoming part of Hardcast and Carlisle affords great opportunity for our employees, customers and for the HVAC industry as a whole. We are all ready to make a bigger impact together.” 

Sal Fasanella, General Manager of Hardcast says, “Gripnail joining Hardcast represents many exciting opportunities to expand resources and broaden our collective footprint in the air-distribution space. This acquisition fits with Hardcast’s plans to provide more complete solutions and support for the HVAC sheet metal industry."
