Steel City Squeeze Connector, AC/Flex/DC

Seven trade sizes, from 1 inch up to 3-1/2 inch: XC 273 (1"), XC 274 (1-1/4"), XC 275 (1-1/2"), XC 276 (2"), XC 277 (2-1/2"), XC 278 (3") and XC 278A (3-1/2"). Sized by trade size of the cable or flexible conduit, and sold individually rather than by the bag or carton.

One fitting covers all three. The XC squeeze connector is rated for AC (armored cable), flexible metal conduit, and DC/MC cable, so an electrician stocking a job with a mix of AC whips and flex drops does not need a different connector for each.

Zinc die cast body. Zinc die cast is a standard indoor/dry-location fitting material and is what you would use for general commercial branch circuit work. For wet locations or corrosive process areas, specify a fitting listed for that environment instead.

A squeeze type clamps the cable or flex between a saddle and the body as you tighten the clamp screws, which grips the armor without threading into the convolutions. That makes it the usual choice when you are terminating AC cable, MC/DC cable, and flexible metal conduit with the same fitting. A screw-in connector engages the flex convolutions and is flex-only; a duplex fitting is for bringing two cables into one knockout. The Steel City XC series is the squeeze type.

It does, in one part-number family: XC 273 through XC 278A covers 1 inch to 3-1/2 inch, all zinc die cast, all under UL file E23018, and all rated for AC, flex and DC. That lets an MRO stockroom carry a single series from small AC whips up to 3-1/2 inch flexible conduit runs rather than mixing brands by size.

XC 274 is the 1-1/4 inch. If you are ordering next size either way, XC 273 is the 1 inch and XC 275 the 1-1/2 inch.
