Photo shows left/right end pieces with 3 inward curving modules.
Use this 16” Inward Curving Extension Module to give a natural looking curve to your waterfall. Multiple modules can be connected to form as large of a waterfall as you would like! These spillways are ideally suited for forming the headwaters of a waterfall/stream feature. They are designed to be installed inside the liner to prevent leaking. Each piece is extremely rugged and includes heavy plastic grating making it easy to completely hide the unit under rock. Note: you need to also purchase the Left/Right End Pieces to make a usable waterfall.
