Abstract
A line trimmer head assembly having a central hub and a body including an annular disc extending circumferentially radially outward from the central hub to removably receive the length of a uniform cross-section line. The disc member is provided with a pair of openings on the disc periphery through which a fixed line length is threaded. The interior portion of the disc is provided with at least two retainer clips having a hook shaped member with an incline ramp surface for cooperating with the portion of the line extending between the two openings. The line is held in place by tension which causes the line to travel down the ramp surface.
