Compatible design for Hayward SPX1091C and WB736660 skimmer assemblies; exact fit with overall dimensions 16.5 x 9.5 x 12 cm, top diameter 16.5 cm and bottom diameter 12 cm to ensure optimal water flow. Durable construction: white, robust plastic that resists pool chemicals, UV exposure, and daily use; reliable performance across multiple swim seasons without cracking or warping. Efficient debris collection: captures leaves, insects, hair, and other floating debris before they reach the filter, helping keep water cleaner and reducing pump load to extend equipment life. Easy maintenance: integrated handle for quick removal; lift, empty, rinse, and replace in seconds without tools. Use scenarios: - Spring pool opening: replace worn skimmer basket to maintain clean water as you start the season. - Periods of heavy debris: catches leaves and debris before they clog the filter during windy or autumn days. - Routine maintenance: simple swap during weekly pool care to keep the filtration system efficient.
