OS-400, a paper-faced composite corner bead from Strait-Flex, beautifully finishes outside 90º corners and is the most cost-effective outside corner bead on the market. This 4 in. corner bead applies with all-purpose compound and features a pre-finished laminated nose ensuring a clean sharp corner. The laminated nose eliminates the risk of damage from a taping knife, will not shrink, and will not fuzz up during sanding. The bead’s outer edge features a diamond punch pattern for easier feathering, faster drying, and the highest bonding strength. The backing of OS-400 is Strait-Flex’s patented composite material creating an incredibly strong corner.
