IS-300

Description

IS-300 is specifically designed for inside 90º corners where there are large framing and drywall irregularities. IS-300, a paper-faced composite corner bead from Strait-Flex, beautifully finishes inside 90º corners and is the second most cost-effective inside stick corner bead on the market. This 3” corner bead applies with all-purpose compound and features a pre-finished laminated center section ensuring a clean sharp corner. The laminated center 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 IS-300 is Strait-Flex’s patented composite material creating an incredibly strong corner.
