Abstract: A string trimmer assembly includes a trimmer head rotatably driven by a drive shaft and defining a cavity, a spool supported in the cavity of the trimmer head and operable to support line to be dispensed, and a flange formed on the spool. The spool includes a through hole for receiving the line, which is dispensable though an opening in the trimmer head. The flange is formed on the spool in a common plane with the opening and with the through hole. The flange separates the line into a first line portion and a second line portion. The first line portion is positioned on a first side of the flange, and the second line portion is positioned on a second side of the flange.
