The History of A-United Automatic Doors & Glass

Seeing a need, Jim and T.J. Hannum founded A-United in 1997, calling it A-United Glass and Construction. In 7 years, they had cornered the market on automatic doors.

Stanley Access Technologies Inc. noticed their success and gave them the right to become an authorized retailer. They were recognized and officially endorsed to supply, install, and service Stanley automatic doors. By 2004, they changed their name to A-Untied Automatic Doors & Glass. Three generations later, they now service and install all types of automatic doors.

Our Company Values


Our customers rely on us to provide quality doors and mechanical components. We offer only durable products that stand the test of time.


No matter the type of automatic or manual door, we can service it. We pride ourselves on the quality of our work and the satisfaction of our customers.


As an Omaha-based family company, we’re dedicated to serving our vibrant community. But it doesn’t stop there. Every community we service is a community we serve.

Why Automatic Doors?

A manual door doesn’t have the ease of use that an automatic door does. An automatic door creates a customer-first experience. You don’t want your customers to notice your doors, you want them to feel that they can enter your business effortlessly. And, with so many different custom options, an automatic door gives your business a personal touch.

Who We Serve

We’ve worked across the region as a commercial door company in Lincoln and Omaha. We do everything from installation, repair, and preventative maintenance. That includes handicap ADA Operator doors, storefronts, and glazing. Our team has installed automatic doors in commercial buildings, medical buildings, and offices.
