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 Sigma Electric ProConnex 1 in. D Die-Cast Zinc Water-Tight Conduit Hub is built to seal and connect rigid or IMC conduits with confidence, indoors or out. This rugged hub combines durability with weatherproof integrity, making it a reliable choice for outdoor electrical enclosures, mechanical rooms, and any wet-location installation.

Why choose the ProConnex 1 in. D Conduit Hub

  • Heavy-Duty die-cast zinc construction delivers superior strength, impact resistance, and long-lasting corrosion protection in harsh environments.
  • Water-tight design ensures a secure, weatherproof connection between conduit and enclosure in wet locations.
  • Versatile conduit compatibility supports both Rigid and IMC conduits, simplifying upgrades or new installations in mixed systems.
  • Professional reliability with UL and CSA listings provides confidence for code-compliant electrical work in commercial and residential projects.
  • Compact 1-inch size fits standard trade-size openings while delivering a robust seal and easy installation.

Ideal uses and practical scenarios

Designed for wet locations, this hub is perfect wherever outdoor durability matters. Install it on outdoor lighting housings, weatherproof electrical boxes, or indoor/outdoor equipment enclosures that require a tight, water-resistant conduit connection. It’s an excellent fit for renovations, new-builds, or service upgrades where a dependable, weatherproof conduit hub is needed.

What makes this conduit hub stand out

Beyond the basic function of joining conduit to enclosures, the ProConnex 1 in. D hub delivers tangible, practical advantages: a weatherproof seal designed for outdoor exposure, durable zinc die-cast construction that resists impact and corrosion, and trusted industry listings that support safe, compliant installations. If you’re upgrading from a less robust hub or installing a new outdoor-fed system, this piece provides a dependable, long-term solution that reduces maintenance and rework.

Tips for optimal installation

  • Ensure the enclosure knockout is prepared to match the 1-inch trade size for a clean, airtight fit.
  • Use proper connectors and gaskets designed for wet-location hubs to maximize water-tight performance.
  • Torque uniformly to achieve a consistent seal without over-tightening, which can damage threads.
  • Verify compatibility with existing conduits and fittings in your install plan to prevent gaps or misalignment.

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.
