Eaton Specification Sheet - ECLK736
36 inch flexible length and stainless steel body enable flexible routing around obstacles without sacrificing durability. This translates to faster installs and fewer field joints in long runs, which reduces leak points and potential corrosion. Application areas include complex conduit runs in hazardous areas such as offshore platforms, chemical plants, and refineries. The male on one end and female on the other simplify field assembly, reducing mis-wiring and installation time while ensuring a secure, continuous seal. NEC/CEC compliance and the NEC hazardous rating of Class I, Division 1 (with Class II/III coverage noted in specifications) provide regulatory peace of mind for critical projects. The 2-1/2 inch trade size supports standard conduit systems, while the 42 inch overall length offers adaptable routing. Compatible with common conduit fittings and field installations, it minimizes special-order delays and supports predictable maintenance cycles. Stainless steel construction delivers corrosion resistance and durable performance in harsh environments, reducing maintenance costs and downtime.
