Feature → Business Impact → Application: The LTB400DC uses FMC conduit with a straight connector profile and insulated zinc die-cast housing, delivering a moisture-resistant, mechanically robust seal that minimizes corrosion risk in harsh environments. This translates to fewer field defects and longer service life on outdoor enclosures and wet-wet areas, enabling reliable operation in chemical plants and mining sites. Application: Ideal for straight runs in equipment cabinets and process lines where space and integrity are critical. Feature → Business Impact → Application: NEC/CEC compliance and Hazardous/Classified Location ratings (Class I, Division 2; Class II/III) provide regulatory peace of mind, accelerating approvals and reducing audit findings. Application: Suitable for regulated facilities requiring certified fittings, such as refineries and utilities. Feature → Business Impact → Application: Conduit type FMC and 4-inch trade size, with a 3.5 in depth and 4.78 in height/width, allow predictable space planning and straightforward mounting in cramped panels. Application: Fit for retrofit or new-build installations where precise dimensions matter. Feature → Business Impact → Application: Insulated design minimizes electric shock risk and supports safer handling during installation. Application: Favorable in environments with exposure to moisture and temperature swings. Feature → Business Impact → Application: UL-listed, zinc-die-cast construction provides durability against impact and corrosion, lowering maintenance costs over the asset life.
