Schluter®-DILEX-KSA features a trapezoid-perforated anchoring leg, made of stainless steel or aluminum, which is secured in the mortar bond coat and provides edge protection for adjacent tiles, and a self-adhesive backing strip which can be bonded to fixed building elements (e.g., door and window frames, bathtubs and shower trays, countertops, etc.). The profile isolates the tile covering from the structure and accommodates movement via the 3/8" (10 mm)-wide, soft thermoplastic rubber movement zone, which also forms the visible surface. The thermoplastic rubber movement zone can be replaced if damaged. DILEX-KSA uses the same anchoring leg as DILEX-KSN to allow for the same appearance throughout an installation. DILEX-KSA also prevents sound bridges, making it ideal for transitions in sound-rated floors.
