The A540 Series ground clamps are key to creating a quality temporary connection for antistatic grounding applications. The clamp features three teeth to penetrate dirt, corrosion, and road grime when in use. The teeth are constructed of stainless steel to ensure lasting operation, and isolated from the clamp handle to allow operators to establish ground and a ground-verification signal in a single clamp action. The A540 also includes a high durability cable and junction box for convenient wiring access during installation and maintenance.
