Surelite Inc. was a bus window manufacturer in Conway, Arkansas.
The company began as the C. S. Sash Company. C. S. Sash was founded by Dave Ward in January 1956 with the help of several key patents. The company began as a Harkrider Avenue bus window and aluminum sash manufacturer associated with the local bus plant Ward Body Works. C. S. Sash became Surelite in 1969, and the company expanded into the insulated and laminated glass business. The company also began to manufacture auxiliary back-of-the-bus heaters, as well as plastic casings for control panels and wheel well covers, for buses. The company also made plastic casings for use in boats and other vehicles. Many of the employees at the plant in the 1970s were college students working flexible hours.
