HGC1M-N72-BLU is a cup style heel grounder designed to discharge static from personnel to ground by connecting the wearer to a grounded walking surface. It features a 1 megohm resistor for current limiting, a 24 inch multi-strand conductive ribbon made of carbon suffused nylon on polyester sewn in a sinusoidal pattern, and a durable 3-layer rubber sole with double life span that will not mark shoes. The blue elastic hook and loop provides a comfortable, secure fit with 3/4" width and good visibility for compliance verification. This UL listed grounder meets the requirements of ANSI/ESD S-20.20, EIA 625, MIL-STD-1886, and MIL-HDBK-263 standards. Ideal for use in ESD-sensitive environments such as electronics manufacturing and assembly areas where personnel grounding is required.
