In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

About Product Overview

This is Southwire's 14/3 Romex Type NM-B WG in a 100-foot coil, built for circuits that need a third conductor - think three-way switch legs, split circuits, or any run where you need two switched hots plus a neutral and ground. The blue jacket sets it apart from standard white 14/3, making it easy to identify at a glance when you've got multiple circuit types running through the same walls or panel.

Each conductor is solid copper, rated for 15 amps and 600 volts, with PVC thermoplastic insulation and a nylon jacket that carries a 90-degree temperature rating. It's flame retardant, UL listed, and rated for both indoor use and direct burial, with sunlight/UV resistance built in - so it holds up whether it's buried in a wall or run somewhere it'll see the sun.

  • 14/3 gauge, 3 conductors, solid copper
  • 15 amp / 600 volt rating
  • 90°C temperature rating
  • Direct burial and UV resistant
  • UL listed, flame retardant
  • 100 ft coil, blue jacket for easy ID

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.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

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 familiar 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.
