These lightweight, free-running, powerful performers are used for sail controls that see lots of action: mainsheet, runner, halyard, and spinnaker systems. A center cage keeps Torlon roller bearings separated and parallel to reduce friction. The sheave center carries primary load, allowing a smaller, lighter weight block. The soft-attachment Loop block has a removable deadend post for attachment to a padeye. Lashings can also be used.\u003c\/p\u003e\r\n","brand":"RIGGINGONLY","offers":[{"title":"Default Title","offer_id":40487084228799,"sku":"HAR3386","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/7987\/0143\/products\/HAR3386.jpg?v=1629478622","url":"https:\/\/justrigging.com\/products\/harken-57mm-double-loop-block","provider":"JUSTRIGGING.COM","version":"1.0","type":"link"}
