Tighten the T-bolt nut until the clamp ends are snug and the joint is fully compressed — over-tightening can distort the band and compromise the seal. Slide the rubber protective cap over the exposed bolt end after tightening to prevent corrosion on the thread.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303486279955,"sku":"SX310N","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-heavy-duty-clamp-for-proseries-sand-filters-w3s210s-w3s310s-sx310n.webp?v=1786088931","url":"https:\/\/poolaroo.com\/products\/hayward_sx310n","provider":"Poolaroo","version":"1.0","type":"link"}
