For use in areas where a hazardous atmosphere may be present, SD series Reelites® provide 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 a single or Y configuration.
