The Hayward SPX1096K skimmer weir is designed for compatible SP1090, SP1092, SP1096, SP1097, and SP1098 skimmer applications and measures approximately 5-3/4 inches by 5-1/4 inches by 1 inch. A properly working weir helps improve surface skimming by controlling how floating debris and surface water move into the skimmer throat.This part is often replaced when the original weir becomes warped, cracked, swollen, or stops moving freely. Replacing a worn weir can noticeably improve surface debris draw and help the skimmer recover the intended action it had when new.This OEM Hayward replacement is a smart maintenance choice for compatible skimmers that need better surface-cleaning performance without replacing the whole unit.
