It replicates the function of a traditional Prusik pulley system while offering enhanced control and consistency during positioning and descent.\u003c\/p\u003e\n\u003cp\u003eThe friction chain design allows fluid movement along the rope, with a release lever enabling accurate speed control during descent. A pulley mounted on sealed ball bearings supports efficient slack management, while separated and curved side plates improve durability and rope interaction. The device locks automatically when the friction chain extends, ensuring secure positioning without additional input.\u003c\/p\u003e\n\u003cp\u003eSuitable for use on both doubled rope systems and single rope setups when used with compatible accessories, the ZigZag offers versatility for different climbing techniques. Its fixed lower attachment point maintains correct alignment with the user, improving handling and control. Built with aluminium, steel, and nylon components, it is compatible with 11.5 mm to 13 mm ropes and meets recognised standards for professional arborist use.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNew item with packaging, but old stock (2022 model)\u003c\/li\u003e\n\u003cli\u003eMechanical friction device for smooth tree climbing movement\u003c\/li\u003e\n\u003cli\u003eFriction chain design for precise and controlled positioning\u003c\/li\u003e\n\u003cli\u003eSealed bearing pulley for efficient slack management\u003c\/li\u003e\n\u003cli\u003eAutomatic locking when the friction chain extends\u003c\/li\u003e\n\u003cli\u003eCompatible with doubled and single rope systems\u003c\/li\u003e\n\u003cli\u003eDurable construction with improved wear resistance\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eAluminium, steel, nylon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e365 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRope compatibility\u003c\/td\u003e\n\u003ctd\u003e11.5 mm to 13 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRope type\u003c\/td\u003e\n\u003ctd\u003eEN 1891 type A low stretch kernmantel ropes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking load limit\u003c\/td\u003e\n\u003ctd\u003e140 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertification\u003c\/td\u003e\n\u003ctd\u003eCE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Fletcher Stewart","offers":[{"title":"Default","offer_id":57739617304959,"sku":"TW-D022AA00","price":125.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/3184\/1151\/files\/Petzl-ZigZag-Mechanical-Friction-Device.jpg?v=1781763857","url":"https:\/\/arbsurplus.com\/products\/petzl-zigzag-mechanical-friction-device","provider":"ARB Surplus","version":"1.0","type":"link"}
