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 6/3 Romex NM-B with ground, a heavier-gauge non-metallic cable built for circuits that need more headroom than standard 12 or 10 gauge wire can give you - think electric ranges, large subpanels, or dedicated 220V loads pulled at a 55 amp rating. The 25-foot length is enough for a short run without buying a full roll you won't use up.

Solid copper conductors with a copper ground carry the current, wrapped in 90-degree-rated thermoplastic insulation and jacketed in Southwire's SlikQuik outer sheath, which pulls through studs and conduit with noticeably less drag than standard NM-B jacketing. It's rated 600 volts, UL listed, and flame retardant, and while it carries sunlight/UV resistance, it's built for indoor use only - not for direct burial.

Good fit for electricians and serious DIYers running new circuits for major appliances or panel feeds where 6-gauge copper is called for on the plan.

  • 6/3 AWG solid copper with ground, black jacket
  • 55 amp rating, 600V, 90°C insulation
  • SlikQuik jacket for easier pulls
  • UL listed, flame retardant, indoor use
  • 25 ft length, 9.3 lbs
  • Made in the USA

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.
