Schluter-DESIGNLINE is a border profile for producing decorative designs in interior wall coverings. Designed to coordinate with the corresponding Schluter-RONDEC profiles for outside wall corners. Schluter-DESIGNLINE has a 1" (25 mm) wide surface area and a thickness of 1/4" (6 mm). It is anchored in the mortar bond coat between tile courses via its cross sectional shape and can be used with thicker tiles by building up the setting material behind the profile. Designline is sold per 8' piece.
