The new Element block. The name hints at its essence: everything that doesn’t contribute durability or strength is stripped away. The result is an economical block that does a Harken job.\u003cbr\u003eElement blocks accept line from 8 - 16 mm. They are offered in singles, doubles, triples, fiddles, and footblocks in 45, 60 and 80 mm sizes. Element blocks introduce sideplates that combine forged aluminum and compound curves for strength. They are simultaneously contemporary and very robust. Element’s design pairs the minimum amount of metal required to protect the sheave with a proven journal bearing. So size for size, Element is priced significantly lower, than our previously least expensive blocks.\u003cbr\u003eSideplates are hardcoat-anodized to resist corrosion. A tough composite bearing sheave resists corrosion for a long service life.\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\"\u003eElement\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\"\u003eModel\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003e45 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\"\u003eSheaves Ø\u003c\/th\u003e\n\u003ctd class=\"col data w-1\/2 py-2 pl-2 text-left product-attribute-value\"\u003e45 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\"\u003ePlain 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\"\u003e12 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\"\u003eYes\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\"\u003e1400\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\"\u003e700\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Harken","offers":[{"title":"Default Title","offer_id":54318874886419,"sku":null,"price":480.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7001\/5507\/files\/45mmHarkenElementBlock.jpg?v=1781960779"},{"product_id":"harken-45mm-black-magic-air-block","title":"Harken 45mm Black Magic Air Block","description":"\u003cdiv class=\"flex px-6 md:pt-6 pb-3 mb-6 md:flex-row border-b-2 border-gray-300 hidden md:block\"\u003e\n\u003ch2 class=\"text-gray-900 text-2xl title-font font-base text-center md:text-left w-full\"\u003eDESCRIPTION\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"card w-full\"\u003e\n\u003cdiv class=\"prose\"\u003e\n\u003cp\u003e\u003cb\u003eHarken 45mm Black Magic block -

A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing. Universal Bearing - . Dynamic and high static load performance. The Ronstan Universal Bearing incorporates our proven 2-stage bearing system. Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction. Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance. Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect. Particularly important for cheek blocks. Alloy cheek plates . Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimisation and the cut-away design minimises weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimising rope wear.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Ronstan","offers":[{"title":"Default Title","offer_id":67869276635411,"sku":"RF44100","price":450.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7001\/5507\/files\/rf44100_jpg.webp?v=1793194349"}],"url":"https:\/\/rigginghk.com\/zh-hant\/collections\/45mm-single-blocks.oembed","provider":"Rigging HK","version":"1.0","type":"link"}
