Paddock’s R-Series Gutters are our most popular gutter style due to its aesthetic free form design, spacious overflow channel, and high-capacity filtered water return tube. These benefits make it virtually ideal for all pools of any size and shape. The R-Series Gutter is a unique application of proven engineering that provides superior performance without restricting creative possibilities. Paddock’s R300 Gutter is the most universal as well, and is perfect for wave pools, plunge pools, lazy rivers, and even heavy-use recreation pools. We also offer a similar profile that is smaller, the R200, which best serves wading pools, fitness and therapy pools, and spas. Each configuration is available in multiple configurations as shown in the diagram.
