We have custom fittings made to fit our wall that will increase the efficiency of any waterpark project. Our three-foot wide skimmers make it easier to circulate water and help keep the surface clean and free of debris. Our movement boxes can handle thousands of gallons of water to ensure the speed of your river. The boxes can handle anywhere from two 3-inch bulkheads up to dual 6 inch bulkheads. Placed strategically, just a few can do a remarkable job.
