Strait-Flex® Introduction

Products > Interior Finishing > Strait-Flex® Introduction

Strait-Flex’s focus for over 20 years has been to identify construction problems and manufacture products which increase production rates, save labor and improve quality. This has led to product innovations such as X-Crack which eliminates ceiling cracks, stick cornerbeads that require no fasteners, durable patches that quickly correct miscut and damaged drywall, and Mud-Pro compound applicators that require no daily clean up.

When it comes to meeting wall and ceiling challenges and delivering peace of mind, ClarkDietrich leads by example. Today, we’re staying at the forefront by refocusing our resources to bring smarter solutions and to better serve our customers.

Strait-Flex, a brand already part of our company, will now officially bear our name. All the same trusted products will be available through ClarkDietrich, which offers an ever-expanding line of products for both framing and finishing.

Whether framing a building or bringing that final fit and finish to your interior walls, ClarkDietrich knows that details matter. That’s why we do a lot of the little things differently – like printing measurements and cut lines directly onto our beads and trims – because it gives you an advantage on the jobsite.
