They also work great for backstay adjusters when used in a high purchase cascade configuration. In addition to being lighter and less expensive than conventional blocks, ring ferrules are also less prone to failure since there are no pulleys to crack or bearings to foul.\u003c\/p\u003e\n\u003ch4\u003eFeatures:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eLighter, smaller than conventional pulley block\u003c\/li\u003e\n\u003cli\u003eA popular alternative for many applications where traditional blocks once ruled\n\u003cul\u003e\n\u003cli\u003eInstead of rolling on a pulley sheave, active line slides on inside smooth surface of ring\u003c\/li\u003e\n\u003cli\u003eAnother line is spliced around ferrule for attaching it\u003c\/li\u003e\n\u003cli\u003eAttachment line is sometimes made as a loop that is luggage tagged onto a padeye or toe rail\u003c\/li\u003e\n\u003cli\u003eFrictional losses are not as big as one might think, especially when using low friction line such as Dyneema\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e100% Pure Aerospace Grade 6061 Aluminum\u003c\/li\u003e\n\u003cli\u003eCNC Machined\u003c\/li\u003e\n\u003cli\u003eLarge diameter flange prevents line chafe\u003c\/li\u003e\n\u003cli\u003eConsistent smooth inside surface radius surface\u003c\/li\u003e\n\u003cli\u003eHardcoat Anodized finish, for rugged protection\u003c\/li\u003e\n\u003cli\u003eMade in Mystic, CT U.S.A.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eMax Line Size - 8mm (5\/16\")\u003c\/div\u003e\n\u003cdiv\u003eBreaking Strength - 5,000 lb (2,270 kg)\u003c\/div\u003e\n\u003cdiv\u003eA - 12.7mm\u003c\/div\u003e\n\u003cdiv\u003eB - 8.9mm\u003c\/div\u003e\n\u003cdiv\u003eC - 31.8mm\u003c\/div\u003e\n\u003cdiv\u003eD - 12.7mm\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e MBS rated as minimum deformation load, or the load at which permanent deformation of the ring begins.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Ferrules start having frictional heating and wear problems when there is significant line movement, so conventional pulleys are still better for applications such as mainsheet and halyard blocks.\u003c\/p\u003e","brand":"Harbor Supply","offers":[{"title":"Default Title","offer_id":47173020778692,"sku":"TY2608","price":16.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/7793\/7092\/files\/FR8_WEB_PIC-1.jpg?v=1793903128","url":"https:\/\/harbor-supply.com\/products\/tylaska-dogbone-db10-aluminum-copy","provider":"Harbor Supply","version":"1.0","type":"link"}
