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.

About Product Overview

This 12-foot box rail from National Hardware is the track that makes a sliding barn door work correctly, giving your door a smooth, stable path to roll on instead of sagging or binding over time. Made from galvanized steel, it's built to handle the outdoor exposure that comes with exterior barn door setups, resisting rust and corrosion far better than a bare steel rail would.

With a 450-pound capacity, it's rated for real doors, not just lightweight decorative panels, so it works for shed doors, garage-style barn doors, and heavier interior sliders alike. The 1-7/8 inch width matches standard box rail trolleys and hangers, making it straightforward to pair with the rest of your barn door hardware kit. Sold as a single rail, so plan your order around your door width and whether you need one length or a run of multiple sections.

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.
