Eaton Specification Sheet - 721
Rugged construction with a malleable-iron body provides durable terminations that resist impact and corrosion, reducing maintenance costs and downtime in busy facility environments. The squeeze-type design enables fast, tool-efficient terminations, cutting installation time and labor costs while improving consistency across panels and cabinets. Non-insulated insulator simplifies field termination workflows and lowers replacement costs when rework is necessary, enhancing overall project efficiency. NEC/CEC compliance and Ordinary/Non-Hazardous Location suitability give engineering teams confidence that installations meet regulatory requirements, minimizing wiring errors and inspection holds. The FMC conduit compatibility ensures seamless integration with standard FMC runs, reducing fit-up challenges and misalignment risks during panel assembly. With a trade size of 3-1/2" and a compact 6.4" length, the 721 supports dense wiring layouts without compromising accessibility or serviceability. The malleable iron body, straight connector design, and non-insulated construction make retrofits and new builds straightforward for OEMs and service teams alike.

FAQs
Begin by confirming the conduit is FMC-rated and clean the mating surfaces. Insert the straight connector fully, then actuate the squeeze mechanism to the manufacturer’s torque spec. Verify alignment and seating before final panel sealing to prevent loosening, leaks, or rework. This approach minimizes field troubleshooting and ensures a solid, code-compliant termination.
Yes. The 721 is designed to meet NEC/CEC standards and is suitable for Ordinary/Non-Hazardous Locations. This compatibility supports regulatory compliance across typical commercial and light-industrial environments, reducing the need for alternative fittings and simplifying inspection processes.
Key specs include conduit type FMC, style Squeeze, material malleable iron, connector type Straight, insulator Non-insulated, trade size 3-1/2", catalog number 721, UPC 784564107213, and a weight around 4.7 lb. It is intended for straight FMC terminations in non-hazardous areas and aligns with NEC/CEC standards.
The 721 is rated for Ordinary/Non-Hazardous Locations and is not specified for Hazardous Locations. For harsh environments, select a connector with appropriate explosion-proof or hazardous-location ratings and verify compatibility with your panel design and local codes.
Expect faster installations due to the squeeze-type design, reduced field rework from better fit and alignment, and improved regulatory compliance with NEC/CEC standards. The durable malleable-iron body also lowers maintenance costs over the life of the panel by extending service intervals and reducing replacement parts.
