ABSTRACT:
A duct assembly tool is provided with "vise grip" type handles to allow the tool to be completely released while it assembles sections of duct. Duct assembly flanges are closed together by gripping members which are rotatable with respect to the tool handles. The gripping members may be disc shaped to allow the tool to be used to straighten bowed duct walls.
