Dayton Sure-Grip & Shore was originally founded in 1924 by Art & Carl Kinnenger with help from Charles Danis and Fred Kramer. Carl Kinnenger held the patent on the snap tie design (to hold formwork together) and Dayton Sure-Grip & Shore was licensed to sell it in the U.S. out of their Downtown Dayton location. In 1953, Danis Hunt Construction acquired Dayton Sure-Grip. After beginning bar support production in 1959, Sure-Grip, Inc is founded in 1960, and the company relocated to Miamisburg, Ohio. In 1975, Dayton Sure-Grip purchased C&M Chemical Co. out of Sycamore, Illinois, beginning their production of chemicals. After the purchase of Superior Concrete Accessories in 1982, the company changed their name to Dayton Superior Corporation.
