The NSI INDUSTRIES 268 is a 3.5-inch steel compression connector designed for securing rigid metallic conduit (RMC) and intermediate metal conduit (IMC) to enclosures, junction boxes, and panel knockouts. Built from steel, it provides a mechanically secure, electrically continuous connection at the conduit termination point. This fitting is a standard trade component installed by licensed electricians during rough-in and panel work on both residential and commercial projects. The compression design ensures a tight, rain-tight-style fit without relying on set screws, reducing the risk of loosening over time.
The NSI INDUSTRIES 268 is suited for conduit termination applications where a reliable steel compression fitting is required. It is commonly used in commercial electrical installations, industrial panels, and residential service entrance work wherever rigid or intermediate metal conduit must be terminated at an enclosure. Electricians reach for compression-style connectors in locations requiring a more secure conduit-to-box connection than a standard set-screw type provides.
Designed as an OEM-style replacement and standard-fit compression connector for 3.5-inch rigid metallic conduit and intermediate metal conduit termination applications.
Installation is performed by a licensed electrician in accordance with NEC requirements for conduit terminations and enclosure entries. Disconnect and lock out all power to the enclosure before beginning any conduit fitting work. Use appropriate conduit wrenches or channel-lock pliers to tighten the compression nut to a secure, snug fit without over-torquing the fitting body. Verify that the conduit is fully seated before completing the connection and restoring power.
