SMACNA expresses appreciation to the many who have offered suggestions for constructive improvement in the fabrication and installation of duct systems. Suggestions for future improvement are welcome. Special thanks  given to those who volunteered their time, gave special knowledge and struggled with development of a consensus that would reflect the needs for a diversified industry. Although standardization intrinsically involves selection, no intention of discrimination against the use of any product or method that would serve a designer’s need equally or better exists.
