The D4 cam is made from a super hard solid Stainless Steel and is highly wear and corrosion resistant. The D4 is compliant with CE Standards, NFPA T and ANSI Z359.4 for the worldwide Rope Access and Rescue markets which typically use 10.5mm\/11mm ropes.\u003c\/p\u003e\n\u003cp\u003eThe D4 Descender features a unique and innovative progressive cam action, which offers control at slow or fast speeds. The progressive cam works by way of one cam operating inside another cam. It is also easy to back-feed the rope through the D4 and therefore it can be used for smooth ascending or for emergency hauling (when used as part of a 2:1 ‘Z-rig’).\u003c\/p\u003e\n\u003cp\u003eThe D4 has a rated load of 240kg (529lb), making it a true Work\/ Rescue Descenders. It is not necessary to build in additional friction to achieve these loads, although it can be useful to do so, for an even higher degree of control in Belay applications. The minimum user weight is 60kg (132lb).\u003c\/p\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with rope diameter (mm):\u003c\/strong\u003e 10.5-11.5mm (7\/16\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanic brake:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of persons:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e(WLL) Working Load Limit (kg):\u003c\/strong\u003e 240\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e(WLL) Working Load Limit (lbs):\u003c\/strong\u003e 529\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI compliant version:\u003c\/strong\u003e As standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSerial numbering:\u003c\/strong\u003e As standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEZYiD:\u003c\/strong\u003e Available on request\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCam material:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Anodised\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApproved Standards\u003c\/h3\u003e\n\u003cp\u003eEN12841, - meets the requirements of ANSI Z359, NFPA 19835kN Slip load Max User Weight: 240kg (530lbs)\u003c\/p\u003e","brand":"ISC","offers":[{"title":"Default Title","offer_id":45158526386444,"sku":"298-1-1","price":185.94,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/2356\/9676\/products\/1-200-1-481-1-RP880-D4-Descender_b16dc208-ef7f-4781-9d8f-ae9ac716e3aa.jpg?v=1708861692","url":"https:\/\/orplexltd.co.uk\/products\/isc-d4-descender-with-panic-brake-240kg-rated-load-11mm-dia-rope","provider":"Orplex Limited","version":"1.0","type":"link"}
