The grounding indicator system has been enhanced with additional features and options providing even more operational and safety benefits. The system is designed to provide a fail-safe assurance of a low-resistance path to ground to dissipate static electricity when transferring flammable liquids or powders to or from taker trucks, railcars, drums, various containers or virtually any other conductive equipment. The new features include an optional HD heavy-duty stainless steel ground clamp, a retractable coiled grounding and monitoring cable, and a quick-connect design for fast field replacement of clamp or cable. The new wide-jaw HD stainless steel clamp provides a universal method of connecting to all common mobile tanks and vessels. The retractable coiled grounding and monitoring cable is color coded blue for intrinsic safety. The Cen-Stat™ cable has a chemical- and abrasion-resistant outer coating which also has antistatic properties. Standard cable extended working length is 32 feet with optional lengths of 16 or 48 feet. A 50-foot self-rewind static ground cable reel with ultra-low resistance slip-ring contacts is also available.The new Quick-Connect feature allows quick and easy field replacement of the HD clamp and/or retractable should they be damaged in service. The process requires no special skills or tools. This eliminates costly system downtime in fast-moving situation like tanker truck or railcar loading stations and reduces overall cost of maintenance and repair.
