Quick Summary

The Eaton EHT4 Service Cap is a rugged threaded aluminum cap designed to seal and protect 1-1/4 inch service entrance heads in industrial electrical enclosures. A common pain point is improper sealing, corrosion, or size-mismatch when finishing service entrances, which this cap mitigates with durable die-cast aluminum and precise threading. It aligns with NEC/CEC standards and UL certification references, making compliance straightforward in ordinary locations. Choosing Eaton supports reliable inventory, scalable installation, and reduced maintenance across electrical cabinets and distribution panels. The combination of threaded connection, aluminum construction, and a 1-1/4 inch trade size makes it a practical, long-term solution for CH series installations in ordinary locations.
