So, our team came up with this truly unique solution – the Cobra Corner Guard which protects the edges of corrugated siding cartons.” “I feel the McPherson Plant has overall done a great job of keeping environmentally friendly activities top-of-mind,” says Tad Radzinski, Founder and President of Sustainable Solutions Corporation and an industry expert in sustainability. Radzinski helps companies develop innovative and practical solutions that reduce environmental impact, improve efficiency and save money. “I have had the opportunity to visit many plants and facilities and the McPherson Plant has gone above and beyond to establish a comprehensive recycling program. The new Cobra Corner Guard product is a fine example of this.” Cobra Corner Guard –Page 2 of 2 News Release Cobra Corner Guard, which went into production this summer, features two injection-molded inribs that act as a strap guide to ensure the banding materials don’t slide off. Further distinguishing the design are the “fangs” that attach or “bite” into the carton and hold it in place. Cobra Corner Guards also are now in use at CertainTeed Siding Plants in Hagerstown, Md., and Jackson, Mich. “The purpose of this project was to offer our sister plants a better functioning corner guard, reduce costs and manufacturing waste from our facility through the use of sustainable tactics,” adds Butcher. “I am happy to report that we accomplished all three goals.” About CertainTeed Through innovation and creative product design, CertainTeed has helped shape the building products industry for more than 100 years.
