A duct assembly tool is disclosed including an elongated frame member; a member pivotally secured to the frame member, and a pair of wheels rotatably secured on the tool. One of the wheels is rotatably secured to the frame member and the other wheel is rotatably secured to the member. In use, the tool is in a first position such that the wheels are behind the assembly flanges of adjacent ducts. The frame member is pivoted, with respect to the pivot member, to a second position where the duct flanges are drawn together to enable positioning of a cleat over the flanges to secure adjacent ducts together.
