Eaton LTK Liquidtight Connector LTBK20045 - Low Profile
Part Number: LTBK20045
Quick Summary
The Eaton LTK Liquidtight connector is a 2-inch FMC fitting designed for fast, reliable enclosure entry in harsh, hazardous locations. Engineers seek compact, space-saving solutions, and this low-profile, 45° connector reduces panel intrusion while maintaining a robust seal. It carries NEC/CEC compliance with NEC hazardous ratings and Canadian certification, ensuring regulatory alignment across North American facilities. This combination supports safer installations, easier wiring, and maintenance-ready assemblies. By pairing durable malleable iron, insulated construction, and precise trade sizing with industry-standard conformance, it accelerates procurement, minimizes rework, and improves system reliability for power distribution, automation cabinets, and process-control networks.

FAQs
LTBK20045 is designed for standard FMC conduit systems and pairs with other LTK low-profile fittings. Its 2" trade size and 45° angle simplify routing in constrained enclosures, reducing the need for adapters or extensions. Proper alignment and a clean seal are key; torque to the manufacturer’s guidance to preserve the insulating and environmental protection features.
LTBK20045 carries NEC/CEC compliant designation with hazardous-location ratings including Class I, Division 2 (and related II/III classifications). It also includes Canadian certification via UL listings, and a hazardous-area area classification of Hazardous/Classified Locations, ensuring regulatory alignment across North American sites and cross-border projects.
Yes. The LTBK20045 is explicitly rated for hazardous/classified locations, including Class I Division 2, with NEC/CEC compliance and Canadian certification. It is well-suited for chemical processing environments where space is limited and reliable sealing, insulation, and durable construction are essential for long-term reliability.
The connector meets NEC/CEC standards for hazardous locations and is rated for Class I Division 2 (along with other divisions). Canadian certification is provided through UL listings, as reflected in the product’s certification documents, ensuring regulatory acceptance for Canadian projects and cross-border installations.
The low-profile design reduces panel intrusion, enabling tighter enclosures and smaller cabinet footprints. This can lower material costs and simplify heat management. Faster, tool-efficient installation reduces commissioning time, while durable malleable iron and insulation deliver longer service life, lowering maintenance costs and minimizing field rework over the system’s lifecycle.
