Eaton Specification Sheet - LNR3
Polypropylene construction and a 1-inch trade size deliver lightweight, non-conductive lining that resists moisture and chemical attack. This reduces component wear, simplifies stock management, and speeds conduit installations, especially in control panels, motor starters, and field installations in ordinary areas. NEC/CEC compliance and UL Canada certification reduce compliance risk in routine electrical installations, providing confidence during audits and inspections. The IF 1273 installation sheet and proven fit contribute to faster panel builds and fewer reworks, translating to lower labor costs and tighter project schedules. Its compact weight of 0.02 lb per unit aids handling and reduces overall cabinet load, improving overall assembly flow. The liner also aligns with the LNR ecosystem, enabling seamless accessory compatibility and streamlined procurement for multi-site projects.
