Southwire L707 Zinc Chase Nipple 2.5 Inches

Product Description

The SOUTHWIRE L707 is a zinc chase nipple designed for use with rigid conduit systems. Also known as a speed nipple, this fitting provides a fast, secure connection point where conduit passes through enclosures, panels, or wall surfaces. The L707 measures 2.5 inches and is constructed from zinc, offering corrosion resistance suited to standard indoor and light commercial electrical installations. Licensed electricians and electrical contractors install this fitting as part of conduit runs requiring a reliable threaded connection at knockout openings.

This chase nipple is used in residential and commercial electrical work wherever rigid metal conduit terminates at a panel, junction box, or enclosure knockout. The 2.5-inch size accommodates standard conduit knockout openings of that trade size. It is also cross-referenced as Madison L-707 and Topaz 757, making it a direct replacement or equivalent substitute stocked under those part numbers at other suppliers.
