{"product_id":"series-60-core-block-halyard","title":"Ronstan Series 60 Core Block Halyard","description":"\u003cp\u003eThe Ronstan Series 60 Core Block is a class-leading halyard block engineered for direct attachment to a mainsail headboard for a 2:1 halyard setup. Featuring sleek, contemporary styling and a sophisticated bearing system, it delivers less than half the friction of the nearest competitor under both dynamic and high static loads. The removable 8mm threaded screw pin at the head and acetal roller allow for versatile spliced line attachment, while the central hub hole doubles as a becket take-off or tie-up point. An alloy rope\/wire sheave version is also available.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eType of Block:\u003c\/strong\u003e Single\u003cbr\u003e\u003cstrong\u003eSheave Diameter:\u003c\/strong\u003e 60mm\u003cbr\u003e\u003cstrong\u003eBreaking Load:\u003c\/strong\u003e 2000 kg\u003cbr\u003e\u003cstrong\u003eMaximum Working Load:\u003c\/strong\u003e 1000 kg\u003cbr\u003e\u003cstrong\u003eMax Rope Diameter:\u003c\/strong\u003e 12mm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 186g\u003cbr\u003e\u003cstrong\u003ePin Diameter:\u003c\/strong\u003e 8mm\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Full block rated load can only be achieved with uniformly distributed load across full length of screw pin — requires 14mm (9\/16\") diameter mast collar post or 14mm (9\/16\") wide mast collar plate\/tang.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eItem No. RF64108\u003c\/p\u003e","brand":"Ronstan","offers":[{"title":"Default Title","offer_id":48278042968296,"sku":"20117832","price":109.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/9065\/8280\/files\/20117832_1.jpg?v=1776722474","url":"https:\/\/boatharbourmarine.com.au\/products\/series-60-core-block-halyard","provider":"Boat Harbour Marine","version":"1.0","type":"link"}
