The ORBIT INDUSTRIES RN-100-C is a close-pattern rigid conduit nipple sized for 1-inch trade size threaded conduit systems. It is designed to connect two junction boxes through knockout openings using standard locknuts, providing a short, secure mechanical connection between enclosures. Constructed from rugged metal, the RN-100-C delivers the mechanical protection required in commercial and industrial wiring installations. Electricians and wiremen use this fitting wherever a close-nipple connection is needed between boxes mounted directly adjacent to one another.
This nipple is suited for use with threaded rigid metallic conduit (RMC) and intermediate metal conduit (IMC) systems. It fits standard 1-inch trade size knockout openings and is a common component in panel, junction box, and enclosure installations across commercial, industrial, and residential electrical work. The close configuration minimizes projection between two enclosures mounted back-to-back or side-by-side.
Designed as an OEM-style fitting for use with 1-inch trade size threaded rigid metallic conduit and intermediate metal conduit knockout openings.
Installation is performed by licensed electricians in accordance with NEC Article 344 for rigid metal conduit and Article 342 for IMC. De-energize all circuits and lock out power before working on any enclosure or panel. Thread the nipple through aligned knockout openings and secure each end with appropriate locknuts torqued to the enclosure wall. Inspect threads for damage before installation to ensure a secure, code-compliant mechanical connection.
