Arlington Industries 846 Single-Screw Duplex Romex/BX Cable Connector, 3/8"

The Arlington Industries 846 is a single-screw duplex connector designed to secure two NM (Romex) or armored (BX) cables through a single 3/8" trade size knockout. Rather than requiring two separate connectors and two knockouts, the duplex configuration lets electricians route a pair of cables into one opening, saving space on crowded panels, junction boxes, and enclosures. The single-screw tightening mechanism provides a fast, secure connection point for each cable while keeping installation straightforward for field crews. Whether used in new construction or retrofit work, this connector delivers a compact, efficient way to bring NM and armored cable into a box.

Key Features

  • Trade Size: Sized for a 3/8" knockout, this connector fits standard electrical boxes and enclosures without requiring oversized openings.
  • Duplex, Two-Cable Design: A single connector body accommodates two cables through one knockout, reducing the number of openings needed on a box and helping preserve box fill space.
  • Single-Screw Connection: Each cable is secured with a single screw, allowing for quick tightening and a dependable mechanical connection during installation.
  • Romex/BX Compatibility: Purpose-built for NM (Romex) and armored (BX) cable, making this connector a versatile choice for both non-metallic and armored cable wiring methods.
  • Space-Saving Layout: By combining two cable entries into one knockout, the duplex design helps installers maximize available panel and box real estate in crowded wiring runs.

Arlington Industries ARL846 – Frequently Asked Questions

1) Can the Arlington 846 connector bring two cables into one knockout?
That is the point of it. The Arlington 846 is a duplex connector, so two NM (Romex) or armored (BX) cables land through a single 3/8 inch trade size knockout instead of needing two separate fittings and two openings. On a crowded panel or junction box where knockouts are already used up, it frees a hole.
2) Does the Arlington 846 work with both Romex and BX, or do I need separate connectors for each?
One fitting covers both. The 846 is built for NM (Romex) and armored (BX) cable, so a crew stocking it does not need a second part number when the job mixes non-metallic and armored runs.
3) I am adding a second circuit to a box that has no knockouts left. Is the Arlington 846 a fix?
Often, yes, if one of the existing 3/8 inch openings already has a single connector in it. Swap that single for the 846 duplex and the existing cable plus the new one both land in the same hole, no new opening drilled or punched in the box. It also helps preserve box fill space rather than adding openings on a crowded enclosure.
4) How does the Arlington 846 clamp the cable, and do I need a tool beyond a screwdriver?
Each cable is held by a single set screw. Push the cable in, tighten the screw, done. No clamp plate, no locknut fiddling on the cable side, and nothing beyond a screwdriver for the screws.
5) Is the Arlington 846 suitable for retrofit work or only new construction?
Both. It is used in new construction and renovation wiring, in residential and commercial installations, and in panels and enclosures where knockout space is limited. Retrofit is where the duplex layout earns its keep, since existing boxes rarely have spare openings.
6) What is the manufacturer part number for the Arlington 3/8 inch duplex cable connector?
Arlington Industries part number 846, the 3/8 inch single-screw duplex Romex/BX connector. That is the number to quote for a distributor order or a submittal.
