This gives our Tii-On range maximum strength and reliability with minimal cheek separation when tied on and loaded up with a Tii-Shackle. The stainless-steel head loop also ensures the block stays in the right orientation when being used.\u003c\/p\u003e \u003cp\u003eHigh Load Sheave This block features a high load stainless-steel sheave. This upgrade offers even faster rolling speeds, higher working loads and lower friction when compared to the standard acetal sheave. The stainless-steel sheave allows the block to be paired with both rope and wire.\u003c\/p\u003e \u003cp\u003eFitting Instructions Tii-On blocks rely on the correct attachment method to give them maximum strength.\u003c\/p\u003e \u003cp\u003eWhen attaching a Tii-on block you must feed the rope around the central axle and through the head of the block.\u003c\/p\u003e \u003cp\u003eWhen possible, double Tii-on blocks should be attached with a crossed\/ through threaded line. See the video below.\u003c\/p\u003e \u003cp\u003eThis is very important, as it keeps the line load pulling the side cheeks together. Only use a non-crossed Tii-Shackle on low-load applications.\u003c\/p\u003e \u003cp\u003eFor further fitting advice please contact us.\u003c\/p\u003e \u003cp\u003eBecket The large central rivet not only reduces the overall weight but also offers a rope-friendly attachment, perfect as a tie-off point when being used in a cascade system.\u003c\/p\u003e \u003cp\u003eBearings Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.\u003c\/p\u003e \u003cdiv class=\"container\"\u003e \u003cdiv class=\"cabDes\"\u003eTechnical Description\u003c\/div\u003e \u003cdiv class=\"col-4 menu units\"\u003eFeatures\u003c\/div\u003e\n\u003cdiv class=\"col-4 menu units\"\u003eMetric\u003c\/div\u003e \u003cdiv class=\"col-4 menu units\"\u003eAmerican\u003c\/div\u003e  \u003cdiv class=\"col-4 menu col-12M\"\u003eBreaking Load\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e43.31 in\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e1100 mm\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eMaximum line Diameter\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e0.31 in\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e8 mm\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eMaximum Working Load\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e11.81 in\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e300 mm\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eLength\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e1.63 in\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e41.5 mm\u003c\/div\u003e \u003cdiv class=\"col-4 menu col-12M\"\u003eWeight\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e0.13 lb\u003c\/div\u003e \u003cdiv class=\"cell col-4 col-6M\"\u003e60 g\u003c\/div\u003e \u003c\/div\u003e","brand":"Allen Brothers","offers":[{"title":"Default Title","offer_id":53606407307636,"sku":"ALNA2032TIIHL","price":117.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/A2032TiiHL-1__09541.jpg.1428984928.jpg?v=1761823811","url":"https:\/\/velasailingsupply.com\/products\/allen-brothers-30mm-dynamic-double-block-tie-on-hl","provider":"Vela Sailing Supply","version":"1.0","type":"link"}
