Pentair Extension Collar | Ring Seat | 85002300 Pool Volleyball ABS Thru-wall pool skimmerThe Pentair Extension Collar (85002300) is the OEM replacement ring seat collar for Pentair skimmers, adjustable to accommodate deck thicknesses up to 3 inches. This collar bridges the skimmer body and the finished pool deck surface, adjusting the throat height to match the depth of the surrounding coping or concrete. When the original collar is cracked, warped, or missing, water can migrate behind the skimmer faceplate and into the deck substrate.
