Green Link Updates KnuckleHead

摘要

The biggest competitor for Green Link Eco-Engineering's KnuckleHead line of rooftop supports is wooden blocks. These have been a traditional solution for raising HVAC units off roofs, but while they are cheap, they often are subject to deterioration. As wood blocks break down, they create debris that often gets pulled into a system. They also require metal fasteners that can find their way into HVAC systems. "We're working hard to replace the old and rotten wood," said Dan Olinger, Green Link's president.
