Eaton Specification Sheet - ECLK1021
With a 21-inch flexible length, the ECLK1021 simplifies conduit routing in tight installations and around obstructions. The business impact is faster, error-free assembly that reduces field labor time and potential leakage points, especially in crowded control rooms or offshore platforms. In application, the 30.25-inch overall length provides room for secure fittings behind equipment bays and inside electrical rooms, supporting scalable layouts in chemical plants and refineries. The stainless steel body delivers robust corrosion resistance, extending service life in aggressive atmospheres and salt spray environments. The business impact is lower replacement costs and fewer maintenance shutdowns, enabling more reliable production. In marine and chemical processing facilities, this translates to improved uptime and lower total cost of ownership. The male one end and female the other end ensure versatile mating with standard conduit connections, reducing unpacking and fitting errors during installation. Application scenarios include panel assemblies, machine enclosures, and field retrofits where 4-inch trade size conduits are prevalent. The result is faster commissioning and less rework, especially in retrofit projects. NEC/CEC compliance and UL listings provide regulatory assurance, shortening design reviews and expediting approvals. In new builds and expansions across oil, gas, and chemical sectors, this reduces project risk and accelerates timelines. The product dimensions—30.25 inches long, 4.94 inches wide and high, 28.4-pound weight—offer a stable footprint and straightforward handling for technicians on dense factory floors.

FAQs
ECLK1021 is designed with a 4" trade size and male-female ends to simplify mating with standard conduit fittings. Consider available clearance behind equipment to accommodate the 30.25 in overall length, and plan routing to leverage the 21" flexible segment for tight bends. Ensure compatible UL-approved components are used, and verify the mounting surface can bear the 28.4 lb weight to avoid undue stress on joints.
ECLK1021 carries NEC/CEC explosionproof ratings suitable for Class I, Division 1 environments and is UL certified for use in hazardous locations. The product page notes area classification as Hazardous/Classified Locations, with UL certifications for US and Canada. These certifications help streamline compliance reviews and reduce the need for site-level testing when designing new installations.
Yes. The stainless steel construction provides corrosion resistance desirable in marine environments, and the Hazardous Location ratings support use in offshore and coastal facilities where exposure to salt spray, moisture, and chemicals is common. When specifying for marine projects, confirm compatibility with local regulatory requirements and ensure the UL/NEC/CEC certifications meet project standards.
The 21-inch flexible segment allows technicians to navigate around obstructions without adding multiple elbows or fittings, reducing assembly steps and potential leakage points. This translates to shorter installation times, lower labor costs, and fewer field reworks, particularly in dense equipment layouts or retrofit scenarios where space is constrained.
The stainless steel body and explosionproof ratings contribute to extended service life in harsh environments, lowering replacement and maintenance costs. UL/NEC/CEC certifications reduce design and approval time during project execution, accelerating timelines. Overall, operators gain improved uptime, reduced maintenance shutdowns, and lower total cost of ownership for hazardous area electrical installations.
