The 3M Front Sole Grounder is a front sole grounder that meets the requirements of ANSI/ESD S-20.20, EIA 625, MIL-STD-1686, and MIL-HDBK-263. It improves floor contact by covering the ball of the foot with conductive rubber. Two D-rings and a clasp provide a comfortable and secure fit. This grounder is tested for electrical performance and is lot numbered for QC traceability. 3M uses time-tested construction techniques including computer controlled stitching, riveting, die cutting, and heat cutting to ensure consistent performance.
The 3M Front Sole Grounder is an adjustable foot‑wear accessory that improves static‑dissipative floor contact by covering the ball of the foot with conductive rubber, elastic D‑rings, and a clasp. It uses a multi‑strand carbon‑suffused nylon ribbon sewn in a sinusoidal pattern to ensure side‑to‑side conductivity and includes a built‑in resistor for current limiting.
Key specifications include a 1 MΩ (or optional 2 MΩ) resistor, black color, two D‑rings, and a <10 Ω sole exterior. The device complies with ANSI/ESD S‑20.20, EIA 625, MIL‑STD‑1686, and MIL‑HDBK‑263, and is traceable by lot number for quality control.
