3M™ Front Sole Grounder -FSG1M
 Front Sole Grounder 
this grounder provides improved floor contact by covering ball of the foot with conductive rubber. two d-ring's 
and a clasp provide a comfortable and secure fit. this quality 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.

How Foot Grounders Work
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 shoe or sock makes electrical contact with 
the skin through perspiration. the ribbon is joined to a resistor which 
limits current should accidental exposure to electricity occur. 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.
