Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Sigma Electric Snap Lock 3/8 in. Die-Cast Zinc Flex Connector for AC and MC, 25-pack delivers a dependable, code-compliant link between armored cables and electrical boxes. Built with a die-cast zinc body, this connector combines rugged durability with efficient installation, making it a practical choice for both new construction and retrofit projects.

  • Precise 3/8 in. diameter designed to fit standard AC/MC flex cable and BX assemblies, ensuring a snug, secure connection.
  • Die-cast zinc construction delivers solid rigidity and corrosion resistance, promoting long-term performance in a variety of indoor environments.
  • Snap Lock design streamlines installation—no screws or extra tools required. Insert, snap, and you’re protected, reducing job time and labor costs.
  • UL Listed for safety and compliance, giving you confidence in both residential and commercial applications.
  • 25-pack bulk provides a consistent supply for multiple runs, ideal for contractors, facilities teams, or ongoing projects.
  • Conduit compatibility supports AC and MC (BX) cable, offering a versatile solution for armored cable installations.

Where this connector shines:

  • Attaching BX/AC or MC cable to outlet boxes, switch boxes, panels, or junction boxes in finished walls, basements, attics, or utility areas.
  • Quick, secure connections in both new builds and renovations where reliable cable protection and grounding continuity matter.

What makes it stand out:

  • The die-cast zinc body resists deformation and provides a sturdy grip on the cable, helping prevent loosening over time.
  • Integrated locking mechanism supports consistent, repeatable performance across multiple connections—especially useful for long runs or dense installation layouts.
  • UL-listed construction offers peace of mind for compliance-driven projects and inspections.

Installation tips for best results:

  • Confirm the cable type (AC or MC) to ensure proper fit and performance.
  • Fully seat the connector in the knockout before engaging the snap-lock to avoid gaps or movement.
  • Keep the bulk-pack packaging intact until use to maintain product integrity and uniformity across all connectors in a job.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
