Overview

The NSI Industries GZB-1 Brass Plated Zinc Ground Clamp is a corrosion-resistant, high-conductivity grounding solution engineered for indoor electrical systems. Designed to grip rigid conduit between 1/2" and 1" in diameter, this clamp secures bare copper grounding conductors with zinc-plated steel screws, ensuring a reliable electrical bond. Constructed from brass-plated die-cast zinc, the clamp’s body resists corrosion in humid or chemically aggressive environments, while the zinc-plated steel screws provide long-lasting clamping force without galling or seizing. The clamp’s compact, die-cast zinc alloy design simplifies installation in tight spaces, such as electrical panels, control cabinets, or junction boxes, where space constraints and safety compliance are critical. Unlike generic grounding clamps, the GZB-1 is optimized for indoor applications, including commercial buildings, industrial facilities, and telecommunications infrastructure, where consistent grounding performance is essential for equipment protection and personnel safety. The clamp’s brass plating enhances conductivity compared to unplated zinc clamps, reducing contact resistance and ensuring stable ground paths even in high-vibration installations. NSI Industries, a trusted U.S.-based manufacturer, produces the GZB-1 to meet stringent electrical safety standards, making it a cost-effective alternative to copper grounding clamps without sacrificing performance. Compatible with standard rigid conduit systems, the GZB-1 is ideal for grounding electrodes, equipment grounding conductors, and bonding jumpers in NEC-compliant installations. Order the GZB-1 for a durable, code-approved grounding solution backed by NSI’s reputation for quality and reliability.
