In accordance with another aspect of the present invention, a bracket is provided for lifting one or more duct sections with a crane. Each of the duct sections has a flange with an opening. The bracket includes a base with a surface and a center point. The base also has one or more bolt receiving openings and one or more externally threaded bolts. Each of the bolts is received in a different one of the bolt receiving openings with at least a portion of the bolt extending beyond the surface of the base. An internally threaded nut is associated with each bolt and adapted to secure the flange of a duct section on the base, when the bolt is received through the flange opening of the duct section. The bracket also includes an eye bolt fixed to the base proximate the center point such that the crane may engage the eye bolt and lift the bracket with the attached duct sections.
