{"product_id":"black-diamond-stopper-9-225209","title":"BLACK DIAMOND Stopper #9","description":"\u003cp\u003eThe \u003cstrong\u003eBlack Diamond Stopper #9\u003c\/strong\u003e is a high-strength aluminum alloy passive protection nut, part of one of the most reliable and long-lasting nut lines in the trad climbing industry. Its \u003cstrong\u003edual-tapered geometry\u003c\/strong\u003e is not accidental: it allows the nut to be used in two distinct orientations, adapting to both regular cracks and flared or shallow cracks where a traditional profile would not offer sufficient contact with the rock.\u003c\/p\u003e\n\n\u003ch4\u003eConstruction and Technical Data\u003c\/h4\u003e\n\u003cp\u003eThe nut's body is made from anodized aluminum, which ensures a \u003cstrong\u003esurface resistant to oxidation and wear\u003c\/strong\u003e even after years of outdoor use. The #9 falls into the mid-to-high range of the series, covering correspondingly sized cracks with a solid profile and a steel cable that ensures robustness for removal and resistance to fall shocks. The color coding allows for quick identification on the rack during ascent.\u003c\/p\u003e\n\n\u003ch4\u003eUse in Trad Climbing\u003c\/h4\u003e\n\u003cp\u003eThis stopper is one of the fundamental elements in any complete trad rack. It is used by placing it in natural constrictions in the rock, where the wedge shape generates friction and mechanical blockage under load. The \u003cstrong\u003edual lateral profile\u003c\/strong\u003e makes it particularly versatile in situations where the crack is not uniform or perfectly parallel. Compared to camming devices, it offers the advantage of low weight and quiet, immediate handling, without moving parts subject to wear.\u003c\/p\u003e","brand":"BLACK DIAMOND","offers":[{"title":"Blue","offer_id":53225486385418,"sku":"225209","price":10.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/4357\/8378\/files\/225209.jpg?v=1781695380","url":"https:\/\/www.verticalshop.eu\/en-it\/products\/black-diamond-stopper-9-225209","provider":"Vertical Sport","version":"1.0","type":"link"}
