Overview
The Desco 17252 non-marring heel foot grounder is a personnel grounding device designed for electrostatic discharge (ESD) protection in controlled manufacturing, assembly, and cleanroom environments. Each unit includes a 1-megohm current-limiting series resistor for operator safety against accidental contact with equipment line voltage. The adjustable 3-layer neoprene rubber construction dissipates static charge without marring shoes or floors, making it suitable for extended daily use in quality-critical applications.
Key Features
- 3-Layer Non-Marring Neoprene Rubber: Interior and exterior dissipative material prevents damage to footwear and floor surfaces
- 1-Megohm Series Resistor: Current-limiting protection for operator safety during accidental equipment contact
- Hook-and-Loop Fastening System: Durable Velcro strap with elastic stretch material adjusts to fit most shoe sizes comfortably
- 30-Inch Conductive Grounding Tab: 8-strand nylon polyester tab ensures reliable electrical connection with operator’s sweat layer
- UL-Listed and Date-Coded: Independently reviewed design with lot traceability for quality assurance and regulatory compliance
- Made in USA: Manufactured in Rochester, New Hampshire with US-based support
