A worn gasket and a new clamp installed together eliminates the risk of a return service call for a weeping niche — and both parts are inexpensive relative to the labour involved. All pool lighting work must be performed by a licensed electrician in compliance with NEC Article 680.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774188912915,"sku":"SPX0580B","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-retainer-clamp-with-screw-and-nut-for-astrolite-series-pool-lights-spx0580b-2.webp?v=1787741245","url":"https:\/\/poolaroo.com\/products\/hayward-astrolite-sp580-clamp-w-screw-nut-washer-spx0580b","provider":"Poolaroo","version":"1.0","type":"link"}
