SEPCO C270A 3/8-Inch Die Cast Zinc Duplex Screw Connector

The SEPCO C270A is a 3/8-Inch die cast zinc duplex single-screw connector engineered to secure two cable runs through a single connector body into an electrical box, panel, or enclosure. Its die cast zinc housing delivers the strength and corrosion resistance electricians expect from a connector that sees repeated field installation, while the duplex configuration lets installers land two cables at one knockout instead of using two separate connectors. A single clamping screw draws the cable tight against the connector body for a secure mechanical and electrical connection, and the compact die cast profile is sized to fit standard box and panel knockouts without crowding adjacent hardware. The C270A is sized for 3/8-Inch cable and conduit applications common in residential and light commercial electrical wiring, where fast, dependable box entry connections are essential to a clean installation.

Key Features

  • Trade Size: 3/8-Inch sizing fits standard 3/8-Inch cable and conduit knockouts for straightforward box and panel entry.
  • Durable Construction: Die cast zinc body resists corrosion and stands up to the wear of repeated installation and field handling on the jobsite.
  • Duplex Design: Accommodates two cable runs through a single connector body, reducing the number of knockouts and connectors needed per box.
  • Single-Screw Clamping: One captive clamping screw secures the cable firmly in place for a fast, reliable connection without extra loose hardware to track on the job.
  • Compact Profile: Low-profile die cast design fits the tight box and panel spacing typical of duplex connector installations.
  • Field-Ready Finish: Die cast zinc construction provides a rigid, corrosion-resistant connector body suited to routine handling and installation.

Technical Specifications

  • Refer to manufacturer documentation for complete specifications.

Typical Applications

  • Residential and Light Commercial Electrical Wiring
  • Securing Cable into Junction Boxes and Panels
  • Conduit and Cable Entry Connections at Enclosures
  • New Construction and Renovation Wiring Projects
  • Panelboard and Load Center Cable Entry

Why SEPCO?

SEPCO builds the C270A from die cast zinc for a connector that holds up to the everyday demands of electrical installation work. The duplex, single-screw design simplifies wiring by letting installers land two cables through one connector body, saving both time and box space on the job compared to installing two single connectors. The rigid die cast zinc body is built to resist corrosion and hold its clamping force over repeated installation cycles. For electricians who need a dependable, straightforward cable connector for 3/8-Inch applications, the SEPCO C270A delivers solid, no-nonsense construction backed by SEPCO's electrical hardware line.

SEPCO C270A – Frequently Asked Questions

1) What does a duplex connector like the SEPCO C270A do that a standard single connector doesn't?
The C270A takes two cable runs through one connector body, so both land at a single knockout. On a crowded panel or junction box that cuts your knockout count and connector count in half compared to installing two single connectors. It's a 3/8-inch trade size fitting with one clamping screw holding both runs.
2) Will the SEPCO C270A fit a standard 3/8-inch knockout in a load center or junction box?
Yes. The C270A is a 3/8-inch trade size connector sized for standard 3/8-inch cable and conduit knockouts in boxes, panels, and enclosures, and the low-profile die cast body is meant for the tight spacing you get in a panelboard or load center.
3) What should I use instead of the SEPCO C270A for a wet or corrosive location?
The SEPCO C270A is a die cast zinc duplex screw connector intended for cable entry into boxes and panels in residential and light commercial wiring. For a damp or wet run on flexible conduit, a liquidtight connector is the right family instead: the Hubbell Wiring PS0509N is a 1/2-inch liquidtight nylon connector, and the Ocal ST145-G is a PVC-coated liquidtight flexible conduit connector for installations where a coated metallic fitting is specified. Both are single-conduit terminations, so you would land each run separately rather than doubling up at one knockout as the C270A allows.
4) Can a Hubbell SwivelLok PS0509N be used in place of the SEPCO C270A duplex connector?
No, they solve different problems. The SEPCO C270A is a 3/8-inch die cast zinc duplex connector that lands two cable runs through one connector body using a single clamping screw. The Hubbell Wiring PS0509N is a SwivelLok multi-position liquidtight nylon connector in 1/2-inch trade size, built for a single run of liquidtight flexible conduit where the entry angle needs to be adjusted at the box. If you need two cables through one knockout in a dry interior box, the C270A is the fitting; if you need a 1/2-inch liquidtight termination, the PS0509N is the one.
5) Is the SEPCO C270A metal or plastic?
Die cast zinc. It's a rigid metal connector body, corrosion resistant and built to hold clamping force through repeated installation, rather than a nylon or plastic fitting.
6) How many clamping screws does the SEPCO C270A duplex connector have, and is there loose hardware to keep track of?
One. A single captive clamping screw draws the cable tight against the connector body, so there are no separate saddles or loose parts to drop in the box. That's the whole clamping mechanism on the C270A.
7) Difference between the SEPCO C270A and the Ocal ST145-G connector?
Material and application separate them. The C270A is a die cast zinc duplex connector in 3/8-inch trade size with a single clamping screw, used for cable entry into junction boxes, panelboards and load centers. The Ocal ST145-G is a PVC-coated liquidtight flexible conduit connector, a corrosion-protected fitting for liquidtight flex in environments where the PVC coating is called out on the drawing. The C270A is the choice when the spec is a standard interior cable connector and you want two runs through one knockout.
8) Do I need to specify anything else when ordering the SEPCO C270A, like a finish or size option?
No options to pick. The C270A ships as one configuration: 3/8-inch, die cast zinc, duplex, single screw. Order by part number C270A.
