Bridgeport 1111 Conduit Chase Nipple 4 Inch

Product Description

The BRIDGEPORT 1111 is a 4-inch malleable iron conduit chase nipple designed to create a short raceway connection between electrical enclosures. Finished in zinc for corrosion resistance, this fitting pairs with a standard locknut to secure conduit runs at panel knockouts, junction boxes, and other enclosures. At 1.625 inches in length, it is sized for close-proximity connections where a full conduit section is not required. Electricians and electrical contractors use this fitting in commercial and industrial wiring installations where code-compliant, low-profile conduit entry points are needed.

This chase nipple is suited for use in conduit installations requiring a direct, flush connection between two enclosures or between an enclosure and a wall surface. Typical applications include panel board entries, pull box connections, and equipment enclosure knockouts. The 4-inch trade size accommodates larger conduit runs common in commercial, industrial, and utility electrical systems. When installed with a locknut on each side of the enclosure wall, it provides a secure, rigid conduit termination point.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits and verify the enclosure is fully powered down before beginning work. Thread the nipple through the enclosure knockout and secure with a locknut on each side; do not overtighten to the point of cracking the fitting. Inspect the zinc finish for damage after installation and apply supplemental corrosion protection if the fitting will be exposed to moisture.
