The Strait-Flex Difference

From the very beginning, Strait-Flex has focused on manufacturing products that solve construction problems. In his 25+ years as a carpenter and professional homebuilder, founder John Conboy encountered numerous opportunities to improve the quality and efficiency of the drywall finishing process. This innovation resulted in the creation of new drywall finishing products that eased installation and empowered drywallers to maintain straight alignments of intricate off angles.

Since 1995, with the introduction of Strait-Flex drywall tape, the Strait-Flex name has continued to grow in recognition, popularity, and trust. Today, as part of the Clark-Dietrich family of companies, the expansive Strait-Flex product line is known for its quality finish and ease of use with construction professionals and builders worldwide.
