Sheet Metal Connectors, Inc. manufactures rectangular fittings, including square throat and heel duct elbows with turning vanes, available in many custom sizes and configurations. Fittings are manufactured per job at our state of the art fabrication facilities. All square throat duct elbows 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. Most 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.
