Schluter®-DILEX-BWB features trapezoid-perforated anchoring legs, made of recycled rigid PVC, which are secured in the mortar bond coat and provide edge protection for adjacent tiles. The profile separates individual fields in the tile covering and accommodates movement via the soft chlorinated polyethylene (CPE) movement zone, which also forms the visible surface. The movement zone is 3/8" (10 mm) wide, matching common movement joint widths, and is thus capable of accommodating relatively large movements. DILEX-BWB is suitable for both residential use and medium-duty commercial applications subject to light mechanical loads (e.g., offices or stores). The profile is also suited for exterior use.
