Heavy‑duty grommet sets sized 11 mm (3/8") inside diameter with a 7 mm (1/4") barrel length, supplied with matching washers. The rust‑resistant finish makes them suitable for heavyweight and outdoor applications such as tarps, canvas bags, utility covers and camping gear. They reinforce deeper holes so cords or ropes feed smoothly and edges resist tearing. Install with compatible 11 mm tools on a hard surface for a clean, long‑wearing set. Ten complete sets per pack.
