Powered dispensing tool
A powered dispensing tool includes a housing, a motor, a rack operably coupled to the motor for powered translation along a longitudinal axis in at least one of a forward direction and a reverse direction, a transmission housing at least partially positioned within the housing through which the rack is extendable, first and second plungers, at least one of which is coupled to one end of the rack, and a first cartridge housing within which first and second material cartridges may be supported in a side-by-side relationship. The first and second plungers are associated with the first and second material cartridges, respectively. The tool also includes a second cartridge housing within which only a single material cartridge may be supported. The first and second cartridge housings are interchangeably coupled to the transmission housing to adapt the tool for use with dual material cartridges or single material cartridges.
