Where possible, use a crossed or through-threaded attachment method to keep the load pulling the side cheeks together. When using a Tii-Shackle, crossed attachments are recommended. Non-crossed attachments should only be used in low-load applications.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Allen","offers":[{"title":"No","offer_id":57196757582199,"sku":"A2040Tii","price":33.74,"currency_code":"GBP","in_stock":true},{"title":"Yes","offer_id":57318664274295,"sku":"A2040Tii-SHACKLE","price":45.61,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/7087\/9863\/files\/A2040TII.jpg?v=1781800451","url":"https:\/\/allenbrothers.co.uk\/products\/a2040tii-single-tii-on","provider":"Allen | Performance Sailing Hardware","version":"1.0","type":"link"}
