Aluminum Alloy Ultralight Dyneema Quickdraw Series

Professional ultra-light Alpine/Extendable Quickdraws designed for Trad Climbing, high-altitude Alpine Climbing, long multi-pitch routes, and winter Ice Climbing. The complete set is tightly assembled with high-strength ultra-high molecular weight polyethylene (Dyneema / UHMWPE) slings and two 7075 aerospace-grade aluminum alloy wire-gate carabiners, featuring a breaking strength of 20kN to 22kN and a weight starting at only 49g per set, offering a top-tier strength-to-weight ratio.

During lead climbing, when facing zig-zag route lines, protruding rock corners, or offset protection points, the extended lengths (25cm, 35cm, 40cm, 50cm) effectively straighten the path, keeping the rope straight and fluid, significantly reducing rope drag against the rock face; when connecting active protection devices like Cams, Nuts, or ice screws, it effectively absorbs rope oscillation, preventing the gear from shifting or pulling out of the crack; at remote belay stations (e.g., using trees or rock horns), it also allows for reasonable extension of protection points to reduce impact forces during a fall.

Equipped with freeze-resistant, non-clogging wire-gate carabiners at both ends, featuring a 23mm wide opening and a widened rope contact surface for high wear resistance and smooth rope feeding; in cold, wet, or sandy environments, the wire gate is unlikely to freeze or jam, ensuring responsive and reliable operation. The Dyneema sling features hardcore characteristics such as ultra-light weight, high abrasion resistance, extremely low elongation, and minimal water absorption (anti-icing). The entire series has passed dual certification for European mountaineering carabiner standard CE EN 12275:2013 and firefighting equipment standard XF494-2023.

Key Configurations

• Straighten route lines, eliminate rope drag: The extended length effectively eliminates zig-zag lines caused by offset protection, significantly reducing rope drag and conserving the lead climber's energy.

• Stabilize active protection devices: When connecting Cams, Nuts, or ice screws, the flexible sling absorbs rope movement, preventing the gear from shifting or pulling out due to tension.

• Ultimate lightweight load: The 12cm short version weighs only 49g, and even the 50cm extra-long version is only about 88g, feeling weightless when hung on gear loops, significantly reducing the load for long big-wall climbs.

• Freeze-resistant, sand-proof wire-gate quickdraws: The 23mm wide opening makes it easy to clip with thick gloves using one hand; the wire gate will not freeze or jam in mud, dust, or cold snow environments.

• Widened contact arc for smooth rope guidance: The carabiner body's contact surfaces with the rope and bolt hanger have been widened and optimized for smooth rope passage, effectively delaying the formation of metal wear grooves.

• Dyneema UHMWPE freeze-resistant, abrasion-resistant sling: Ultra-high molecular weight polyethylene fiber has extremely low water absorption and extremely low elongation, remaining flexible without absorbing water in cold, snowy conditions, and is durable.

• Authoritative dual safety certification: The entire series is certified to CE EN 12275:2013 mountaineering quickdraw specifications and the XF494-2023 firefighting equipment standard, ensuring a strong and reliable structure.
