Appleton SD Series static discharge grounding Reelites provide convenient, safe grounding for vehicles, portable machines and equipment operating in hazardous atmospheres. The SD Series provides a retractable grounding cable and clamp for easily and safely dissipating static electrical buildup, reducing the chance of a spark and resulting explosion. These lightweight, rugged steel Reelites can be mounted to the ceiling, wall, or with base down to a clean, unpainted conductive surface to ensure electrical continuity through a frame. They’re available with steel, nylon‑jacketed steel or rubber‑covered copper cable in lengths from 50 to 100 feet, in either single or Y configuration.
