Contractor's Guide: The Dollars & "Sense" of Choosing a Duct System is a resource for understanding the economic impact of selecting a spiral duct system. The guide demonstrates the economic impact to the contractor's bottom line with a scenario highlighting the differences between two configurations for a hypothetical $100,000 job. According to the company, the analysis shows how the scenario with the lowest material cost (often chosen for its low bid price) is not the scenario that yields the most profit. Inside the literature is a chart with several configuration options, ranging from a loose erector set style to a complete manifolded design. The chart highlights the differences in the designs and applies a price and labor index to illustrate the impact of the different choices. A detailed discussion on how, when, and where to consider using the different configuration options is included in The Contractor's Guide.
