Eaton Crouse-Hinds ECLK636 Coupling - NEC/CEC Class I/II
Part Number: ECLK636
Quick Summary
The Eaton Crouse-Hinds ECLK636 coupling is a 36-inch flexible conduit connector designed for hazardous locations. In field installs, long runs can introduce ignition risks, misrating concerns, and costly downtime when wrong fittings are used. This model meets NEC/CEC requirements and carries Class I Division 1, Class II Division 1, and Class III ratings for hazardous areas. With forged brass construction and a 2-inch trade size, it offers installation versatility, robust corrosion resistance, and long-term cost efficiency. This is particularly valuable for engineers sourcing explosion-proof fittings that combine reliability with ease of maintenance in harsh environments. Its 42.5 in overall length and 36 in flexible section give installers room to maneuver through tight spaces while maintaining performance.
