There he met his future wife, Mildred Hildebrand, who was working as a secretary at the local USO, went on to work at Georgia Tech to help Cal get an engineering degree and would ultimately join Cal on the Board of Directors of Automated Building Components, Inc. Jureit was trained as a cartographer and sent to Australia, where he was assigned the job of making relief maps from plywood and clay for use as pilot briefing tools during WWII.

In 1955, Jureit developed and patented the most famous version of his Gang-Nail connector plate, the first metal tie that required no nails, screws or glue.

Starting with this patent, Jureit founded Gang-Nail, Inc in 1956, later renamed Automated Building Components, Inc. (ABC) in the early 1960s and was Chairman & CEO until his retirement in 1979.

Through Cal's persuasion his brother William ("Bill") F. Jureit, an attorney and accountant, left his law practice in the early 1960s to join ABC as Executive Vice President until becoming CEO in 1979.

Prior to his invention, roof truss production was difficult and time-consuming, requiring highly skilled carpenters to make precise cuts and toe-nail two adjoining pieces wood together.

White, former dean of engineering at the Georgia Institute of Technology, commented that "The whole notion about affordable housing and productivity increases came about because of [Jureit's] invention."

[3] Automated Building Components, Inc went public in 1961 and grew to be the largest company in its industry having operations around the world manufacturing connector plates, machinery, roof/floor trusses, and roof tile, as well as providing computerized engineering services.

Additionally, he continued his interest in his love of Pipe organs and the music they create as his Coral Gables home was built around one back in the mid 1960s.
