FAQs
Yes. STG 4 is specifically manufactured for 1-1/4 inch trade size conduit, integrating with Myers hubs to provide a consistent grounding path. Follow the IF 1461 instructions for proper mounting and sealing to ensure hazardous-location compliance.
STG 4 carries NEC/CEC compliance and area classification for Hazardous/Classified Locations, along with UL certification for grounding equipment. It also aligns with Class I Zone 1, Division 2, Class II and III requirements, and NEMA ratings 3, 3R, 4, 4X, 12.
Ideal for chemical plants, oil and gas facilities, wastewater treatment, and other chemical or offshore environments where hazardous area grounding is required. The 1-1/4 in zinc Myers hub supports robust bonding for stainless or coated conduits in harsh conditions.
NEC/CEC compliance ensures the installation meets national safety standards, while UL certification confirms the device is tested for grounding integrity in hazardous locations. Together, they simplify approvals, reduce risk of compliance failures, and support long-term reliability.
The rugged zinc construction minimizes corrosion-related replacements, and the design supports faster field installation, reducing labor costs. With verified hazardous-location ratings, projects experience fewer downtime events and smoother regulatory inspections over the equipment’s life cycle.
