Backed by more than 50 years of innovation, Sheet Metal Connectors, Inc. manufactures all its rectangular fittings in most sizes and configurations. Radius duct transition angles are manufactured in the USA on our union shop’s state-of-the-art fabrication equipment. All fittings are fabricated with stiffening beads on duct sizes 19” wide and larger which have more than 10 square feet of unbraced panel. Fittings shall be beaded unless the duct will have an insulation covering or an acoustical liner. This requirement is applicable to 20 gauge or less in thickness and 3” W.G. or less. The vast majority of fittings are fabricated with Pittsburgh seams and are available completely assembled with all accessories (reinforcement, vane & rail, etc…) installed. Fittings are also available knocked down to reduce shipping and handling costs.
With an emphasis on providing quality workmanship, we are proud to offer radius duct transition angles. If you would like to know more about them, contact us and we will be happy to speak with you.
