Abstract: A combination tool for installation and crimping TDC clips for fastening sections sheet metal fabrication one to another having first and second levers. The levers are secured at a common pivot point with the levers each having opposing first and second jaws. The first jaw means has a cross-sectional configuration which is substantially similar to the cross-sectional configuration of the TDC clip. The second jaw pivotally opposes the first jaw for securing the TDC clip for placement and is configured so as to provide a surface for crimping the TDC clip once the clip is positioned.
