Type: 90-degree inside corner piece. Material: Satin anodized aluminum. Purpose: It is designed for use with the Schluter RONDEC profile (model RO80AE) to finish and protect tiled inside corners, eliminating the need for mitered tile edges. Tile Compatibility: Accommodates tiles that are 5/16-inch (approx. 8 mm) thick. Features: Includes an integrated joint spacer to ensure a uniform grout line between the tile and the profile. I have 22 of these available
