A duct boot hanger, called the Speedi-Bootâ„¢ hanger, is designed to save on installation time and costs, and deliver improved indoor air quality and energy efficiency in residential and commercial buildings, says the company. The heavy-duty galvanized metal frame, with foam gasket and construction debris cover, is said to eliminate boot deformation, fasten securely to reduce energy loss and intake of poor-quality air, improve sealing process for one-hour fire rating, and prohibit construction materials from entering duct.
