The leading manufacturer of rectangular fittings in many sizes and configurations, Sheet Metal Connectors, Inc. makes concentric duct transitions, which are also known as centerline transitions, in our state-of-the-art fabrication facilities. 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 come beaded, except when they 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.
Founded more than 50 years ago, we are proud to stand behind our made-in-the-USA products. If you would like to know more about concentric transitions, contact us and one of our team members will be happy to speak with you.
