Hayward [OEM] SP1089 Basket Skimmer W Collar (SPX1088GA) modular The 1 2 inch to 4 The 1 2 inch to 4 inch range gives this tool practical value because service work often involves different component sizes that still benefit from non marring grip A larger replacement like this is especially useful when the problem is no longer isolated to one small internal part and the complete valve itself has become the better service path The SPX1088GA is a practical OEM replacement for compatible Hayward skimmers that need renewed basket support and cleaner long term operation Helps capture leaves and larger debris with proper seating support
