Cornerstone Proudly Uses Goods Made in America

Tags:

Craftsmanship, quality, and a commitment to keeping it close to home.

TL;DR:

Our kits are built with U.S.-made materials like high-density concrete block, honed limestone countertops, and Primo Kamado grills. This commitment to quality, local jobs, and American craftsmanship is evident.

Why It Matters

Buying American-made products isn’t just about where something comes from — it’s about knowing what goes into it.
When you choose a Cornerstone kit, you’re supporting U.S. manufacturing, local jobs, and a standard of quality that’s easy to see and feel.

Not a Political Statement—Just a Practical One

Supporting American-made products isn’t about left or right. It’s not about tax policy, tariffs, or who’s to blame. It’s about something simpler and more universal: choosing to help our neighbors, our communities, and our country thrive—one purchase at a time.

No matter your views, buying local and American-made products is a habit that helps everyone. It keeps dollars circulating close to home, supports fairness, quality, and independence, and is something we can all do without needing to agree on anything else.

Built Here, Built Right

  • Block and stone: High-density, through-body colored concrete block, manufactured in the Midwest
  • Countertops: 2″ thick natural Indiana limestone, honed for beauty and durability.
  • Appliances: Primo Kamado grills — proudly made in Missouri — and weather-ready stainless steel components from Summerset in California.

Better Quality Control, Faster Answers

Working with American manufacturers means shorter supply lines, fewer delays, and the ability to address questions or issues quickly. It also means materials that meet or exceed U.S. standards for safety and durability.
