Abstract
A hand tool for installing clips to abutting edges of ducts and for crimping the clips to secure the ducts together is comprised of a rectangularly shaped base plate including pairs of opposed rollers mounted thereon with their axes perpendicular to the plate. A gap between the rollers is approximately the same size as the width of the combined edges being secured together. A raised pusher member pushes a clip which is resting on the plate into place and the same is crimped by the rollers when the tool is drawn back. A handle is located on the reverse side of the plate for manually moving the tool.

A hand tool for installing clips to abutting edges of ducts and for crimping the clips to secure the ducts together comprising:
- a rigid flat planar and elongated base plate having a front surface and a back surface;
- handle means mounted on said back surface adjacent one end of said base plate;
- a raised pusher means mounted on the front surface adjacent said one end of said base plate;
- a pair of opposed rollers rotatably mounted on the front surface adjacent the other end of said base plate, said rollers being rotatable about axes perpendicular to said base plate and being spaced from each other on either side of a substantial centerline of said front surface so as to leave a gap between the other peripheries of said rollers which gap overlies said centerline and in alignment with said pusher means.
