About Form-A-Key Products

High-Quality Concrete Products Since 1964

Founded in 1958, Cardinal Manufacturing Company is a family-owned and operated, custom roll-forming company dedicated to delivering high-quality parts at competitive costs. In 1964, Albert Weisbach founded a new division of Cardinal Manufacturing Company known as Key-Kold, Inc. Key-Kold, Inc. began producing Metal Keyway under the trade name “key-kold”. Form-A-Key Products took this popular product, improved upon it, and introduced the first Form-A-Key joint in 1975.

Key-Loc® Joint, the most advanced Metal Keyway on the market, was introduced in 1981. Even today, Key-Loc® is the superior Metal Keyway available – making Form-A-Key a leader in the construction industry.
