ABSTRACT:
A tool for assembling duct sections wherein a gear is rotatably attached to a housing and engages an apparatus with at least one rack. The tool has a pair of duct engaging clasps, at least one of which is integrally attached to the rack apparatus. The other duct engaging clasp may be attached to the housing or attached to a second rack which opposes the first. To assemble and join duct sections, one duct engaging clasp engages one section of duct and the other engages a second section of duct. The gear is then rotated such as to draw the duct engaging clasps together and thereby the duct sections for permanent fastening. After fastening, the gear is rotated in a direction so as to separate the duct engaging clasps. The duct engaging clasps are then disengaged.
