Foot Grounder Choices P/N: See Data Sheets Cup Style Grounder: Provides two grounding soles for double the product life span. Standard Grounder: Provides one grounding soles and an elastic strap around the heel. Toe Grounder: Fits high heels. The grounding sole is under the toe instead of the heel. Sole Grounder: Maximum grounding contact with sole under the toe and heel. Foot grounders discharge static from a person to ground by connecting the person to a grounded walking surface. A conductive ribbon placed inside the wearer's sock makes electrical contact with the skin. The ribbon is joined to a resistor. The other end of the resistor is joined to a conductive sole. This sole contacts a grounded ESD floor mat or ESD flooring system. Foot grounders must be worn on both feet to maintain ground contact while walking.
