FAQs
Yes. The LTBK5090 is specified for FMC conduit and features a 1/2 inch trade size with a 90° angle, designed to integrate with common FMC fittings and standard enclosures. Its low-profile footprint helps fit into tight panel spaces, while remaining compatible with existing fastening patterns and installation practices used in industrial facilities.
The connector is rated for Hazardous/Classified Locations per NEC/CEC, including Class I, Division 2; Class II, Division 1 and 2; Class III. It is insulated and made of malleable iron, offering robust protection against environmental ingress. These ratings support compliance during audits and reduce risk when used in hazardous-area installations alongside UL-certification.
Industries with stringent safety and regulatory requirements—such as chemical processing, oil and gas, and heavy manufacturing—benefit most. The low-profile 1/2" FMC liquidtight connector enables reliable terminations in compact equipment cabinets, pump skids, and in-panel junctions where space is at a premium and hazardous-location compliance is mandatory.
LTBK5090 carries NEC/CEC compliance and hazardous-location ratings, including Class I, Division 2 and related Class II/III classifications, complemented by UL certifications for hazardous areas. These certifications simplify regulatory approvals, enhance product traceability, and reduce risk during procurement and installation by ensuring third-party validation.
Using LTBK5090 can lower maintenance costs through durable materials (malleable iron) and insulated construction that resist harsh environments, reducing replacement frequency. The low-profile design saves panel space and simplifies future inspections. Standard 1/2" FMC sizing lowers inventory needs and speeds up future repairs, improving overall project ROI.
