Sheet Metal Connectors, Inc. manufactures 90 degree square duct elbow fittings in a range of sizes and configurations. Square throat radius heel elbows are produced using state-of-the-art fabrication equipment in our yellow label union shops. Fittings are manufactured with stiffening beads on duct sizes 19” wide and larger which have more than 10 square feet of unbraced panel. Fittings come 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 majority of our fittings are fabricated with Pittsburgh seams and are available completely assembled with all accessories (reinforcement, v corners, etc…) installed. 90 degree square duct elbows are also available knocked down to reduce shipping and handling costs.
