Bridgeport Fittings 621-DC2 Duplex Strap Type AC/MC Connector, 3/8" Cable, Zinc

The Bridgeport Fittings 621-DC2 is a duplex strap type AC/MC connector built to join two armored cable (AC) or metal-clad cable (MC) runs to a single 3/4" knockout using one compact zinc connector body. Sized for 3/8" cable, this duplex design reduces the number of knockouts needed in panels, junction boxes, and enclosures, saving space and installation time on commercial and residential wiring jobs. The zinc construction provides a durable, corrosion-resistant fitting suited for everyday electrical rough-in work.

Key Features

  • Trade Size: Sized for 3/8" AC/MC cable, matched to a 3/4" knockout for standard box and enclosure openings.
  • Duplex Strap Design: Terminates two separate 3/8" AC/MC cables through a single connector and knockout, reducing box fill and simplifying multi-cable terminations.
  • Durable Construction: Zinc body resists corrosion and provides long-term mechanical strength for demanding rough-in and retrofit applications.
  • 3/4" Knockout Fit: Engineered to seat securely in standard 3/4" box and enclosure knockouts for a tight, reliable connection.
  • Space-Saving Layout: Consolidating two cable entries into one knockout helps electricians maximize usable panel and box space in crowded installations.

Bridgeport Fittings 621-DC2 – Frequently Asked Questions

1) Can the Bridgeport 621-DC2 take two AC/MC cables through one knockout?
That's the whole point of it. The 621-DC2 is a duplex strap type connector that terminates two separate 3/8 inch AC or MC cables and seats in a single 3/4 inch knockout. On a crowded panel or junction box that halves the number of openings you have to punch, and keeps multi-cable terminations tidy.
2) Will the 621-DC2 work with MC cable, or is it only for armored cable?
Both. It's listed for armored cable (AC) and metal-clad cable (MC) in the 3/8 inch trade size, which is the common size for 14/2 through 12/3 residential and light commercial MC runs. Two runs land in the one connector.
3) What's the part number to order for a Bridgeport duplex 3/8 inch AC/MC connector?
621-DC2. It ships in one configuration only, the 3/8 inch cable size, so there's no handing, finish, or length to specify. If you need single-cable terminations instead, you want a single strap type connector rather than the DC2 duplex.
4) I need a connector for 1 inch flexible metal conduit, not armored cable. Is this the right fitting?
No. The 621-DC2 is built for 3/8 inch AC/MC cable only. For 1 inch FMC, the Thomas and Betts 306 straight Tite-Bite connector is the fitting for that job. For 1 inch liquidtight, look at the RACO 4734 SWIVEL-LOK multi-position connector in nylon.
5) Why use a duplex connector instead of two single AC/MC connectors?
Two reasons that matter on the job: fewer knockouts and less box fill. Running two 3/8 inch cables into one 3/4 inch opening frees usable space in a crowded panel or junction box, and it's one fitting to install instead of two. Where space isn't tight and cables enter from opposite sides, two singles are still the simpler route.
6) Is the Bridgeport 621-DC2 body zinc or steel?
Zinc. That gives you corrosion resistance plus the mechanical strength to hold two cables in a strap-type clamp, which is why it holds up in damp rough-in and retrofit work as well as dry indoor panels.
