The body is precision-engineered from 7075 aerospace-grade high-strength aluminum alloy and stainless steel, weighing only about 112g, combining extreme lightweight construction with exceptional durability.\u003c\/p\u003e\n\u003cp\u003eFeaturing an innovative integrated dual-pulley rope guide structure, it significantly reduces metal wear during rope entry and exit, making the ascent process extremely smooth and effortless. Equipped with a rope-retention safety closure system, it completely prevents the main rope from accidentally slipping out during lateral movement or swaying in the air; the opening latch is specially designed with a small hole for a cord, allowing for rapid, one-handed operation. The high-strength steel cam features three dedicated self-cleaning mud channels, ensuring reliable rope-grabbing braking power even in harsh conditions such as icy, muddy, or wet environments. The angled lower connection hole allows the chest ascender to sit flush against the chest of the harness, ensuring a straight and efficient vertical ascent path.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eIntegrated Dual-Pulley Low-Resistance Design:\u003c\/b\u003e Dual rollers guide the main rope in and out, drastically reducing friction and preventing wear between the rope and the ascender body.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eRope-Retention Safety Closure:\u003c\/b\u003e A fully enclosed design eliminates the risk of the rope accidentally disengaging during lateral shifts or significant swaying.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eQuick-Release Cord Hole:\u003c\/b\u003e The cam lever features a hole for an auxiliary cord, enabling quick, one-handed opening and closing operations.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cp\u003e\n\u003c\/p\u003e\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eSteel Cam with Three Mud-Cleaning Channels:\u003c\/b\u003e Durable, high-hardness stainless steel cam with three grooves to quickly expel mud and ice, ensuring a secure, non-slip grip.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eOptimized Angled Connection Hole:\u003c\/b\u003e The bottom hole is geometrically optimized to keep the chest ascender flush against the harness chest bridge, preventing misalignment during ascent.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eAuthoritative Firefighting Standards:\u003c\/b\u003e Complies with the XF494-2023 firefighting fall protection equipment standard, with a 5kN working load for safety and reliability.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eTechnical Specifications\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eMain Material:\u003c\/b\u003e 7075 Aerospace-grade aluminum alloy, stainless steel (cam and pulleys)\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eCompatible Rope Diameter:\u003c\/b\u003e 8 – 13 mm\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eRated Load:\u003c\/b\u003e 5 kN\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eNet Weight:\u003c\/b\u003e Approx. 112 g\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eCertification:\u003c\/b\u003e XF494-2023 Firefighting Fall Protection Equipment Standard\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eStructural Features:\u003c\/b\u003e Integrated dual pulleys, three mud-cleaning channels, rope-retention safety lock, auxiliary cord hole\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eApplications:\u003c\/b\u003e SRT ascent, caving, rope access positioning, firefighting rescue, tree climbing (arboriculture)\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"NJTX","offers":[{"title":"紅","offer_id":45892000972935,"sku":"J013AA00","price":191.0,"currency_code":"HKD","in_stock":true},{"title":"橘色","offer_id":45892001005703,"sku":"J013AA01","price":191.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/1740\/1991\/files\/Page11_Img03_IM178_16983394-29a0-4c82-9fdf-57a17924fffd.jpg?v=1789817620","url":"https:\/\/treeholic.co\/en\/products\/%e9%8b%81%e5%90%88%e9%87%91%e9%9b%99%e6%bb%be%e8%bc%aa%e8%83%b8%e5%bc%8f%e4%b8%8a%e5%8d%87%e5%99%a8","provider":"Treeholic","version":"1.0","type":"link"}
