Eaton Crouse-Hinds LNR4 Conduit Liner - NEC/CEC
Part Number: LNR4
Quick Summary
LNR4 conduit liner is a polypropylene non-metallic conduit liner used in ordinary locations for 1-1/4\" conduit runs. Installers often struggle with debris ingress and alignment in rugged environments; this liner minimizes contamination and helps maintain proper bend radii. This product aligns with NEC and CEC standards and is rated for Ordinary/Non-Hazardous Locations, supporting safe, compliant installations. Designed for Eaton Crouse-Hinds systems, its polypropylene construction offers chemical resistance, lightweight handling, and cost-effective maintenance for durable electrical installations. By simplifying line-side assembly and reducing rework, it supports faster project timelines and lowers commissioning costs for panel builders and integrators. As a reliable non-metallic conduit liner, it complements common electrical installs where NEC/CEC compliance and ordinary-location protection matter most.
