Schluter-DILEX-BT is a maintenance-free, prefabricated movement profile used to bridge expansion joints. Schluter-DILEX-BT offers secure edge protection for surfaces exposed to foot traffic as well as vehicular traffic and is, therefore, suited for use in warehouses, production facilities, shopping centers, airports, train stations, and parking garages, or for coverings cleaned with machines. One variation of the profile, Schluter-DILEX-BT/O, can be used to create expansion joints at floor/wall transitions. A second variation, Schluter-DILEX-BTS, is added to completed surface coverings.
