To ensure proper anchoring, the type of cavity anchor must be adapted to the type of facing brick and masonry used. For traditional masonry, round dowels are used. For bonded facing bricks, flat dowels (Isolfix NT-P type) should be used to maintain joint thickness. And for narrow facing bricks (Eco Brick type), L-shaped flat dowels (Isolfix NT-L type) should be used to ensure sufficient anchoring in the masonry.
