The Delden Story



1955 Gene Renner works as a commissioned salesman for Dierks Lumber Company in Kansas City, MO. Dierks begins selling Ro-Way garage doors by Rowe Mfg. Co. of Galesburg, IL.

1956 Gene partners with his father, Elmer Renner, to sell overhead doors as R&R Garage Door. Gene’s wife, Freida Renner, keeps the books. With sales of only $65,000 in his first year, Gene plans to get out of the business.

1957 A destructive tornado in Kansas City spurs many door sales, interrupting Gene’s plans to drop the door business. He changes the company name to Renner Supply, selling builders’ hardware and garage doors, installing Ro-Way and Wagner doors.

1964 Renner buys a Lincoln Door Clamp from Berry Door (Birmingham, MI) and creates Delden Manufacturing Company (Kansas City, MO) with Dick Wright, Harry Link, and Elmer Renner as minority partners. Delden is named for Dee Layne, Dennis and Denise, his three children. With the clamp, Delden can make an 8x7 wood overhead door for less than $30.

1966 Gene and Dick Wright form Renner-Wright Corporation in St. Louis, making garage doors with a Lincoln Door Clamp.

1969 Delden begins producing fiberglass and aluminum garage doors.

1971 Renner-Wright becomes Delden of St. Louis, as Dick Wright sells his share to Renner.
