Foot grounders provide a continuous ground path between an operator and a properly grounded ESD protected flooring. These foot grounders are designed for use on standard shoes. They can be easily adjusted to fit most individuals. Desco's foot grounders have a lining that prevents carbon marks on shoes. Foot grounder models have discrete resistors built into the contact strip. The product has been tested to ESD STM97.2 - floor materials and footwear voltage measurement in combination with a person. It is a suitable ESD footwear component in flooring - footwear system when used as the primary grounding method (< 3.5 x 10^7 ohm per ESD STM 97.1 floor materials and footwear-resistance measurement in combination with a person). - Hook and loop stretch hook and loop fastening system. Size adjustable material expands to fit most shoe sizes comfortably and flex during walking. Tear resistant rubber with inner scrim. Reinforced material prevents tearing - increasing the service life of foot grounder. 30 Inch long, 8 conductive strand nylon polyester grounding tab. Additional conductive material provides reliable connection with operator's sweat-layer. Non-marring interior layer will not mar operator's shoes. Date coded. Provides lot traceability to ensure quality control and tracking information.
