This Widemouth Skimmer/Return differs from standard skimmers because of its wide mouth that helps for it to efficiently collect debris. It is guaranteed to provide maximum performance and will last for a lifetime. Skimmers act as the suction machine of all unwanted debris, so the wider the skimmer the more debris it can pick up. The skimmer is modeled with deep body and locking basket for effective skimming action. The widemouth skimmer is carefully made of durable two-piece materials for extended life. This skimmer includes 1 1/2 FPT and 1 1/2 hose adapter.
