Crouse-Hinds ACB50 Steel Insulated AC/FMC Straight Connector

The Crouse-Hinds ACB50 is a 1/2-Inch steel insulated straight connector engineered to terminate armored cable (AC) and flexible metal conduit (FMC) into a 0.52 - 0.92-Inch cable/conduit range. Part of the Crouse-Hinds ACB Series, this connector delivers a secure, code-compliant termination point for AC and FMC raceway systems in commercial, industrial, and residential electrical installations. Its steel body provides mechanical durability while the insulated throat protects conductors from abrasion as wires pass through the fitting during installation and service. Electricians rely on the ACB50 for a dependable, straight-line connection wherever armored cable or flexible metal conduit needs to transition into a box, enclosure, or panel. The straight body configuration simplifies inline routing, making the ACB50 a practical choice for electricians working in tight junction boxes, panels, and enclosures where a compact, direct termination is required. Because it is engineered as part of the broader Crouse-Hinds ACB Series, the ACB50 offers consistent fit, thread engagement, and performance alongside other sizes in the same product family, giving contractors a reliable go-to option for AC/FMC terminations across a jobsite.

Key Features

Crouse-Hinds ACB50 – Frequently Asked Questions

1) Will the Crouse-Hinds ACB50 connector fit 1/2-inch flexible metal conduit and 14/2 armored cable?
The ACB50 is a 1/2-inch trade size AC/FMC connector and accepts cable or conduit outside diameters from 0.52 to 0.92 inch. Standard 1/2-inch FMC and common armored cable fall inside that window, so measure the jacket OD on what you are terminating: anything under 0.52 inch or over 0.92 inch needs a different size in the ACB Series.
2) What is the closest straight FMC connector to the Crouse-Hinds ACB50 if a 1-inch trade size is needed?
The ACB50 is a 1/2-inch steel insulated straight connector for AC and FMC in a 0.52 to 0.92-inch cable/conduit range, so it will not terminate 1-inch flexible metal conduit. For that opening, the Thomas & Betts 306 is a straight Tite-Bite connector described as a 1-inch FMC fitting. One difference to note before ordering: the T&B 306 is non-insulated, while the ACB50 has an insulated throat that protects conductor insulation as cable is pulled through.
3) Can the Crouse-Hinds ACB50 be used for a liquidtight flexible conduit run?
No. The ACB50 is built to terminate armored cable (AC) and flexible metal conduit (FMC) into a box, enclosure, or panel, with a steel body and insulated throat. For liquidtight flexible conduit, a purpose-built liquidtight fitting is required, such as the RACO 4734 SWIVEL-LOK, a 1-inch Type B liquidtight multi-position connector in nylon. The RACO 4734 also articulates to multiple positions, where the ACB50 is a fixed straight-body fitting for direct inline termination.
4) What does the insulated throat on the ACB50 actually do for me on the job?
The insulated throat lines the opening the conductors pass through, so wires are not dragged over a bare steel edge when you pull cable through the fitting during install or later service. On armored cable terminations that is the point where conductor insulation usually gets nicked. If you are buying a non-insulated fitting instead, you are relying on an anti-short bushing to do that job.
5) Should I use a straight AC/FMC connector or a 90-degree one?
Straight is what the ACB50 is: a direct inline termination of AC or FMC into a box, panel, or enclosure. Use it where the conduit can approach the enclosure head on. If the cable has to turn hard right at the box because you are tight to a wall, ceiling, or an adjacent enclosure, a 90-degree AC/FMC connector keeps the bend out of the box instead of forcing it inside the gutter space.
6) Is the Crouse-Hinds ACB50 steel or die-cast zinc?
Steel body. That is the mechanical-strength choice for raceway terminations that get pulled on repeatedly, and it is a point to confirm against the drawing if your spec calls out steel fittings rather than die-cast.
7) When does an insulated AC/FMC connector matter instead of a non-insulated one like the Thomas and Betts 306?
The Crouse-Hinds ACB50 carries an insulated throat specifically to protect conductor insulation from abrasion as wires are pulled through the fitting during installation and service, which is what inspectors and specs often call for on armored cable terminations into panels and enclosures. The Thomas & Betts 306 straight Tite-Bite connector is a non-insulated FMC fitting, so where a job calls out an insulated throat, the ACB50 is the one that answers it. Note the two are also different trade sizes, the 306 being a 1-inch FMC fitting.
8) Does buying the Crouse-Hinds ACB50 also get me the box it terminates into?
No. The ACB50 is the fitting itself, the termination point where armored cable or flexible metal conduit enters a box, enclosure, or panel. The enclosure is a separate line item. One example of a box side of that connection is the RACO 232MSCM, a 4-inch square welded box 2-1/8 inches deep with an M bracket and a STAB-IT connector built in. Order the ACB50 when the enclosure is already set and only the AC/FMC termination is needed.
9) If I'm standardizing AC/FMC fittings across a whole building, will other sizes match the ACB50?
Yes. The ACB50 is part of the Crouse-Hinds ACB Series, which is built for consistent fit and thread engagement across sizes, so crews handling 1/2-inch and larger terminations work with the same fitting style throughout. That is the usual reason a property or facilities group specifies one series rather than mixing brands box to box.
10) What part number do I order for the Crouse-Hinds 1/2-inch insulated AC/FMC straight connector?
Order Crouse-Hinds ACB50. That is the manufacturer part number for the 1/2-inch steel insulated straight connector, and it is a single configuration, so there are no finish or option suffixes to specify.
