Abstract: A string trimmer head having a frame and a flexible cutting member attached to the frame. The frame is a one-piece member with two hook sections on opposite sides of the frame. The hook sections each have a receiving slot with an entrance facing towards a substantially closed bottom side of the frame and a closed end at a substantially open top side of the frame. In one embodiment the receiving slots have different widths to accommodate attachment of different diameter flexible cutting members to the frame. In another embodiment, the frame is adapted to have either one flexible cutting member attached to it or two flexible cutting members attached to it with the flexible cutting member(s) extending from the frame in uniform patterns in either arrangement.
