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

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

The Simpson Strong-Tie 3 in. H x 6 in. W 12 Ga. Galvanized Steel Elevated Post Base is built to outlast harsh outdoor conditions while keeping your deck posts perfectly aligned and elevated above grade. The 12-gauge galvanized steel construction delivers lasting strength, resisting corrosion and wear from the elements.

Key features that stand up to the job

  • Material and gauge: 12-gauge galvanized steel for superior durability and corrosion resistance.
  • Dimensions: 3 in. tall by 6 in. wide base footprint for stable, reliable support.
  • Elevated design: Keeps posts above ground moisture, increasing the lifespan of treated lumber and reducing rot risk.
  • Load transfer: Engineered for dependable transfer of deck loads into footings, improving stability during wind and dynamic use.
  • Brand trust: From Simpson Strong-Tie, a recognized name in structural connectors and outdoor build components.

Ideal applications

  • Residential decks, porches, and exterior stairs where posts must be elevated for moisture control and proper drainage.
  • Outdoor structures that require a robust, corrosion-resistant post base that won’t sag or shift over time.

Why elevation matters

Elevating posts above soil and concrete helps prevent moisture wicking, reduces staining, and provides a predictable, level starting point for framing. The galvanized finish guards against rust and enables a clean, professional appearance for long-lasting outdoor projects.

Installation guidance (practical tips)

  • Adhere to local building codes and Simpson Strong-Tie installation guidelines for fasteners and post sizing.
  • Pair with appropriate posts and footings; ensure the base sits securely on a solid footing before attaching joists.
  • Use compatible fasteners designed for exterior use to maximize longevity and performance.

Maintenance and longevity

  • Regularly inspect for corrosion or debris around the base, especially in coastal or high-humidity environments, and clean as needed to maintain performance.

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.
