Strait-Flex Mid-Flex is a muddable, paper-faced composite, flexible corner bead that adjusts to any angle to create perfect inside and outside 90 and off-angle corners. The composite structural backing provides strength for durability and impact resistance. The heavy-weight, diamond punched paper provides maximum adhesion for an even lay-down of the paper edge and reduced edge cracking. Strait-Flex Mid-Flex is packaged in 100 ft. rolls that can be cut to the desired length in the field to minimize scrap loss.
