The Challenger line includes several frame configurations — verifying the number on the original part ensures a correct fit. If the base is broken and the number is unreadable, cross-reference your pump's model number against Pentair's Challenger parts diagram to confirm this is the correct base for your specific pump configuration.\u003c\/p\u003e\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53960106901779,"sku":"355305Z","price":58.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_355305z","provider":"Poolaroo","version":"1.0","type":"link"}
