| Description: |  | Jaws designed for sheet metal work; specifically the metal edges of duct work using "drive cleat" connections.  A primary function is to clamp duct work sections together to facilitate installing the "drive cleats."
Known example does not include the "stop" screw which would allow the distance between the jaw edges when the tool is "locked" to be pre-set to a predetermined gap. |  |
