Orbit Industries RN-250-400 Rigid Conduit Nipple 2.5 in

Product Description

The ORBIT INDUSTRIES RN-250-400 is a galvanized steel rigid conduit nipple rated for 2.5-inch trade size applications. It connects two junction boxes or enclosures through threaded knockout openings using standard locknuts. Designed for use with threaded rigid metal conduit (RMC) and intermediate metal conduit (IMC), this nipple delivers solid mechanical protection for conductors at the connection point. The galvanized steel construction provides corrosion resistance in demanding environments. Licensed electricians and electrical contractors typically install this fitting as part of a raceway system in commercial, industrial, and residential electrical installations.

This nipple is suited for any installation requiring a short, direct conduit run between two enclosures, junction boxes, or panel knockouts. The 2.5-inch trade size fits standard RMC and IMC knockout openings of matching size. The 4-inch length makes it appropriate for connecting boxes with moderate separation or wall thickness between them. It is commonly used in commercial wiring, industrial control panels, and service entrance work where metallic raceway systems are required by code.

Compatibility

Designed as an OEM-style fitting for use with threaded rigid metal conduit and intermediate metal conduit systems using 2.5-inch trade size knockout openings.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for rigid metal conduit systems. De-energize all circuits before working in or around any enclosure. Hand-thread the nipple into both knockout openings and tighten locknuts securely on each side to maintain the equipment grounding path. Inspect threads for damage before installation to ensure a clean, secure fit.
