{"product_id":"position-lock-ring-modular-filter","title":"Sta-Rite Position Lock Ring, Modular Filter","description":"\u003cp\u003eThe Sta-Rite 27001-0054S is the position lock ring, also called the Posi-Lok ring, for System 2 modular media filters. It is the genuine Sta-Rite part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe filter tank is built as an upper and a lower half. The lock ring goes around the joint between them and holds the two together against the pressure inside. Everything the filter does depends on that ring staying intact.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe inside diameter is approximately 16 in. The inner lip, the part that grips the tank flange, is approximately 3\/4 in. thick. Sta-Rite used more than one ring size across the modular filter range, so compare those measurements with your old ring before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSun and years of clamping load make the plastic brittle. A ring that has cracked, split or lost its shape has to be replaced rather than coaxed back on, since it is the only thing keeping a pressurized tank closed.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48625721639124,"sku":"STA-051-2790","price":207.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_5f82a8e7-e099-4e75-bc9d-0cd65e10510a.png?v=1788689926","url":"https:\/\/www.activepoolsupply.com\/products\/position-lock-ring-modular-filter","provider":"Active Pool Supply","version":"1.0","type":"link"}
