JTD Spiral is a sister company of Morris Sheet Metal Corp that specializes in producing spiral ducts, oval ducts, and dual wall ducts (both round and oval). The company was created by the original founders of Morris Sheet Metal, brothers Dan, Tim, and Jim Morris. Around ten years ago, as Morris Sheet Metal was rapidly expanding, so was their usage of the spiral duct. Thus, JTD Spiral was created.
Today, JTD alone is responsible for a substantial part of the overall profit and produces around 1.5 million pounds of spiral annually. Besides meeting the needs of their parent company Morris Sheet Metal, JTD sells spiral duct all across the country. Clients from Iowa, Maryland, Oklahoma, and Texas have been dealing business with JTD for years now, and are satisfied with both the quality and cost of their service. Speaking of quality, all spiral ducts manufactured by JTD are per current SMACNA standards.
