Moving air around a home can be a complicated process. Several different sections of pipe-both insulated and uninsulated-need to be used. The Majestic UD4 4-inch Uninsulated FlexDuct for Outside Air is just one of the many options offered by Majestic. This particular FlexDuct is 4" (100 mm) in diameter. The model number refers to two 42" (1065 mm) sections. The FlexDuct is uninsulated, so it won't be moving incredibly hot air around. It's specifically designed to work well with outside air. Since 1993, Majestic has been providing quality products for the construction of home fireplaces and hearths. This FlexDuct is no exception!
