Eaton Specification Sheet - PLG105 SA
Copper-free aluminum construction delivers corrosion resistance and easier handling, reducing weight by about 0.9 pounds compared to traditional fittings. This translates to safer, faster installations in demanding facilities where frequent replacements are a concern. The 4 inch trade size ensures seamless compatibility with standard rigid/IMC conduit runs, minimizing the need for adapters and costly rework on site. The square-head design allows quick, tool-efficient mounting with common wrenches, which lowers labor costs and reduces commissioning time. Rated for Hazardous/Classified Locations, the PLG105 SA supports Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III environments, enabling compliant installations in chemical plants, refineries, and mining operations. The copper-free aluminum body provides outstanding durability in harsh environments while keeping the installation weight manageable for maintenance crews. Dimensions and weight—4.5 in length and height, 2.44 in width, 1.08 lb—facilitate planning and inventory control. NEC/CEC conformity and UL certifications reinforce audit readiness and vendor reliability, reducing procurement risk. The product’s robust construction also supports long service life, reducing downtime and replacement costs as part of a broader safety program and compliance strategy.
