The Aquascape Quad-Spill Straight Stacked Slate Topper makes it easy to add a unique, customized fountain to any location. Simply add a straight stacked slate wall base (not included) to create a water feature that is sure to impress. Water is pumped through three separate water outlets at the top of the wall before spilling over the textured feature. The impressive natural-looking finish looks and feels like real stone, and the durable, lightweight fiber-resin composite construction is built to last. Multiple units can be stacked and combined for endless design configurations.
