How is Edmunds different from other gage manufacturers? Perhaps it's an attitude. After all, our family name is on each and every product that we make. There's a certain level of pride that goes along with that. That's probably why we are vertically integrated. We perform every phase of manufacturing our gages in-house. We have more control this way, and can truly say that we own the technology. It's our energy. Skill. Knowledge. And experience. It makes us more accountable to you.
