Manufacturer Irwin Tools marked the fourth annual National Tradesman Day Sept. 19 by encouraging Americans to thank industry workers.

“Irwin   Tools established  National Tradesmen Day  in  2011 to both celebrate  the exceptional work of  America’s skilled  trade professionals and  thank   them    for their  continued  contributions,”  said the HVAC construction tool company’s senior vice president, Rich Mathews.  “We all  owe  a  debt of  gratitude  to         professional  tradesmen. Without these  hard-working men and  women, our  nation’s infrastructure and  our way of  life  would come to  a screeching halt.”
