Steel City XC Connector, Screw-In, AC/Flex, DC, Insulated

The Steel City XC screw-in connector is made for armored cable (AC/flex) and flexible metal conduit, and it carries an insulated throat. The screw-in design threads into the cable convolutions rather than clamping with a squeeze saddle, so you seat it by turning it into the cut end of the armor and then tighten the locknut at the box.

Seven trade sizes: 3/8, 1/2, 3/4, 1, 1-1/4, 1-1/2 and 2 inch, ordered as XC 840, XC 841, XC 842, XC843, XC844, XC845 and XC846. Size to the cable or flex, not the box knockout. Sold each, so count one per cable termination.

The XC connector is an insulated-throat fitting, which protects the conductors where they pass through the connector. Whether a red-head anti-short bushing is still required at the cut armor depends on the cable type and your inspector's reading of the code, so many installers still fit one on Type AC.

A screw-in connector like the Steel City XC threads directly into the flex convolutions, so it goes on fast with one hand and no separate clamp screw to strip. A squeeze (saddle) connector grips the outside and is the usual pick when you need to land on flex that is already cut short or when the spec calls for a clamp-type fitting. Both land in a knockout with a locknut.

Yes, the XC screw-in insulated connector runs across the common range from 3/8 inch for fixture whips up to 2 inch for larger flex runs, all in the same zinc die cast, insulated, UL listed family. One part family for the whole facility keeps the stockroom simple and gives your crews a consistent install method.

Zinc die cast. That suits dry indoor and general-purpose branch circuit work in boxes, panels and enclosures; it is not a raintight or wet-location fitting.
