Eaton Crouse-Hinds ECLK512 Coupling - NEC/CEC Hazardous Locations
Part Number: ECLK512
Quick Summary
Coupling solutions from Eaton Crouse-Hinds ECLK512 deliver reliable, flexible connections for hazardous-area installations. Operators and maintenance teams often struggle with rigid runs that complicate routing and increase downtime; this model adds a 12 inch flexible length to simplify layouts and speed repairs. It is built to meet critical certifications for safe operation in harsh environments, including NEC/CEC compliance, Class I Division 1 hazardous ratings, and UL Canada certification. The combination of forged brass construction and a 1-1/2 inch trade size delivers durability and compatibility with standard conduit fittings. This translates to reduced maintenance costs, faster commissioning, and safer, code-compliant infrastructure for industrial facilities.
