IS-300 is designed for 90-degree inside corners where speed and strength are needed and/or where large framing irregularities need to be overcome. 

IS-300 diamond-punched paper edging allows for easier feathering, faster drying, and high bonding strength, which assures even lay-down of the paper, providing maximum adhesion without rippling or blistering. Apply with all-purpose joint-compound.

Features

• Vertical or horizontal inside 90° corners
• Clean installation
• Composite PVC provides a tough, durable corner
• Perfect corners without paper fuzz-up during finishing and sanding
