After years of heat, pool chemistry and thermal cycling, that hardware often will not come back tight or evenly loaded. Fitting the kit rather than reusing corroded originals is what keeps the reassembled header sealed.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634447003860,"sku":"HAY-151-0034","price":67.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_5eb945fc-486e-48f8-b461-e40d4db659f3.jpg?v=1788830639","url":"https:\/\/www.activepoolsupply.com\/products\/header-hardware-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
