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\n\n\u003cp\u003eTorlon is a registered trademark of Solvay Advanced Polymers L.L.C.\u003c\/p\u003e","brand":"Harken, Inc.","offers":[{"title":"Default Title","offer_id":43455625592866,"sku":"H3389","price":207.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0267\/1208\/0418\/files\/H3389-Harken-45mm-Aluminum-Loop-Block_ad29eed2-6c51-47c5-a953-56e3f35cd4b0.jpg?v=1743618422","url":"https:\/\/sailingservices.com\/products\/black-magic-block-45mm-single-loop","provider":"Sailing Services","version":"1.0","type":"link"}
