Crouse-Hinds CRS5050 – Frequently Asked Questions

1) What does a back-to-back box connector like the Crouse-Hinds 5050 actually do?
The Crouse-Hinds 5050 joins two electrical boxes directly to each other, with no length of conduit in between. You thread it into a knockout on each box so the two enclosures sit tight together. It's the fitting to reach for when two boxes are mounted back to back or side by side and there is no room (or no reason) to run conduit between them.
2) Will the Crouse-Hinds 5050 fit a 1/2 inch knockout?
Yes. The 5050 is a 1/2 inch trade size fitting, sized for standard 1/2 inch conduit knockouts and box openings. On a standard box that is the 7/8 inch knockout commonly stamped for 1/2 inch trade size fittings. For any other trade size you need a different part number in the line.
3) I need to connect flexible metal conduit into a box, not join two boxes together. Is the Crouse-Hinds 5050 the right fitting?
No. The Crouse-Hinds 5050 is a 1/2-inch die cast zinc back-to-back box connector, built to join two electrical boxes directly to each other without a length of conduit between them, so there is no raceway termination on it. For terminating flexible metal conduit at a box, the Thomas & Betts 306 is a straight Tite-Bite connector for 1 inch FMC in a non-insulated version. Use the 5050 only where two enclosures sit against one another.
4) Is the Crouse-Hinds 5050 made of steel or zinc?
Die cast zinc. That gives you a corrosion-resistant body for damp or demanding electrical environments without the plating you'd depend on with a steel fitting. It's the only material offered on the 5050.
5) Can I use the 5050 instead of a short conduit nipple and two locknuts between boxes?
That's exactly the substitution it's built for. Rather than cutting a chase nipple or short conduit stub and running locknuts on both ends, the 5050 is a single purpose-made fitting that couples the two enclosures directly. Fewer pieces to assemble in a tight panel or enclosure bank, and a repeatable result across a run of boxes.
6) What is the exact Crouse-Hinds part number to order for the 1/2 inch back-to-back box connector?
Model 5050 is the manufacturer part number, and it is a single configuration: 1/2 inch trade size, die cast zinc, back-to-back. There are no finish or size options to specify.
7) What should I use instead of the Crouse-Hinds 5050 in a wet or washdown location?
The 5050 is a die cast zinc back-to-back box connector for 1/2-inch knockouts and is not a sealed raceway fitting. Where the connection has to keep liquid out, a liquidtight fitting is the different tool for the job: the RACO 4734 is a SWIVEL-LOK series 1 inch Type B liquidtight multi-position connector in nylon, supplied 100 per pack. The 5050 remains the choice for dry box-to-box ganging in tight spaces.
8) If I am buying a new box anyway, do I still need a separate connector like the Crouse-Hinds 5050?
It depends on what the box already has. Some boxes ship with a connector built in, such as the RACO 232MSCM, a 4 inch square welded box 2-1/8 inches deep with a STAB-IT connector and an M bracket. The Crouse-Hinds 5050 is a standalone 1/2-inch die cast zinc fitting whose job is coupling two existing enclosures directly together, so you would add it when the boxes are already in place and need to be ganged without a conduit run.
9) Is the Crouse-Hinds 5050 a medium-voltage cable connector?
No. The 5050 is a 1/2-inch die cast zinc back-to-back box connector, a mechanical fitting that couples two enclosures for commercial, industrial, and residential wiring work. Conductor-level medium-voltage connections call for a different product class, such as the 3M SC0001 stem connector rated up to 35 kV for 2 and 1 AWG. The two are not interchangeable: one joins boxes, the other joins cable.
10) Is the 5050 suitable for commercial and industrial work or just residential?
Both. It's used in commercial and industrial installations, panel and enclosure assemblies that need tight box spacing, and residential wiring alike, on new construction and renovation work. The die cast zinc body is what carries it into the harsher environments.
11) Do I also need a box with a built-in connector, or does the 5050 work with plain knockout boxes?
The 5050 works with ordinary boxes that have 1/2 inch knockouts. A box with an integral connector, such as the RACO 232MSCM 4 inch square welded box with a STAB-IT connector and M bracket at 2-1/8 inches deep, serves a different purpose, that being cable entry at the box itself. The 5050 still handles the box-to-box coupling.
