The blocks are very efficient that you can adjust the sail and sheet tension perfectly. Harken Zircon blocks are made for jib sheets, spinnaker sheets and mainsail sheets.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe Zircon blocks are the most efficient Harken has ever made. The performance is unmatched due to the ceramic ball bearings. With the Zircon blocks the energy loss caused by friction is extremely low. Even lower than the amazing Carbo range from Harken. So especially when the breeze backs off, the Zircon blocks let you ease.\u003cbr\u003eZircon bearings are more than 700% stronger than stainless bearings. This becomes evident when you need to ease a sail in very light air. You feel even the slightest fluctuations in sheet load.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable class=\"additional-attributes w-full\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eSeries\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003eZircon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eSheaves Ø\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003e57 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eNumber of sheaves\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eBearing\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003eBall bearing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eMax rope diameter\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003e10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eSwivel\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eCam\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eRatchet\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eBreaking Strength (kg)\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003e900\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"border-b border-gray-300 last:border-b-0\"\u003e\n\u003cth class=\"col label w-1\/2 py-2 text-left text-fg-secondary font-normal product-attribute-label\" scope=\"row\"\u003eSafe Working Load (kg)\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003e300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Harken","offers":[{"title":"Default Title","offer_id":54318750695699,"sku":null,"price":695.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7001\/5507\/files\/hk2195.jpg?v=1781953985","url":"https:\/\/rigginghk.com\/zh-hant\/products\/harken-57mm-zircon-block","provider":"Rigging HK","version":"1.0","type":"link"}
