Grommet
A small tube-shaped insert set into the holes of a racket frame that the strings pass through, protecting them from the frame's edges.
Definition
A grommet is a small plastic or synthetic tube fitted into each string hole around a racket's frame. The strings thread through these grommets rather than touching the frame directly, so the grommet cushions the string and shields it from the sharp edges of the drilled holes.
Grommets are usually supplied as moulded strips that follow the curve of the frame, sometimes combined with a protective bumper along the head. They wear down over time and can crack or flatten, so worn grommets are commonly replaced during a restring to help prevent premature string breakage.
