Create a beautiful, natural-looking waterfall with this durable one-piece waterfall spillway, ideal for building Just-A-Falls style water features. Constructed from strong roto-molded material, this spillway is designed for long-lasting performance and easy installation.

The patented Spliner Lock system securely attaches the liner to the spillway without the need for silicone, bolts, or tools. Dual pre-installed 2″ spinweld inlets allow for easy plumbing from either end, and a plug is included for the unused inlet.

A 4″ diffuser tube runs along the bottom of the spillway, allowing water to enter from either end—or both—and distribute evenly across the entire width for a smooth, consistent waterfall. For an even more natural appearance, the inside of the spillway can be filled with gravel to help create a seamless, natural-looking cascade.
