Wagner-Smith Equipment’s founders started doing business in 1917 as The Charles M. Kelso Company. Over the years, we’ve changed names and expanded the services we provide. But what hasn’t changed is our focus on customer satisfaction.

Today, we design, build, sell, rent and service overhead and underground line-stringing equipment and tools for the electrical line industry across the nation.
