Product overview
Skimmer Lid Extension Collar for U-3 Skimmers, Replacement for Pentair — an aftermarket cover / lid dimensioned to drop into Pentair skimmer and cleaning circuits without modification. In service it closes and seals the housing while allowing access for service. It is a wear item: the sealing face distorts and fasteners corrode, so the cover no longer seats evenly.
