KeeneStone Cut masonry cavity-drainage device includes 1- and 2-inch thicknesses for cavity-wall requirements. The device is a three-dimensional, geometric-patterned core with a high-loft fabric laminated to one side. The fabric compresses to fill the cavity, allowing it to change thickness as much as 1/2 inch to prevent mortar blockage by catching and holding mortar droppings. Moisture passes through, and weep holes remain open.
