Carabiner Hook JS Custom 28kn Screw Locking D Shape High Tension Aerospace Grade Aluminum For Outdoor Hiking/climbing CN;ZHE 69g

Technical Parameters

Core Advantages

• High Strength Meets Lightweight:
• Compared to steel hooks (typically weighing over 150g), the 69g aerospace aluminum material significantly reduces equipment burden, making it ideal for long-distance climbing. Meanwhile, the 28kN breaking strength meets the safety requirements for industrial-grade and high-risk routes.
• D-Shape Structural Advantage:
• The D-shaped design directs the load primarily onto the spine opposite the gate, offering a higher strength-to-weight ratio than standard O-shaped hooks. Its larger gate opening facilitates easy connection with ropes, harnesses, or various equipment.
• Screw-Lock Safety:
• The manually rotating sleeve features a simple and reliable design that resists jamming from sand and mud. Compared to auto-locking carabiners, users can visually confirm the locked status, effectively preventing operational errors.

Applications

• Mountaineering & Rock Climbing:
• Used as a primary connector (locking carabiner) between the harness and protection points, suitable for lead climbing, top-rope belaying, or setting up anchors.
• Caving & Canyoneering:
• In harsh, wet, and muddy environments, the reliability of the screw-lock mechanism surpasses that of some auto-locking carabiners with complex structures. It is ideal for connecting ropes to descenders (rappel devices).
• High-Altitude Work & Rescue:
• Utilized in industrial rope access, wind turbine maintenance, high-altitude cleaning, or emergency rescue systems. It serves as an essential component for connecting lifelines to harnesses.
• Outdoor Hiking & Camping:
• Although its strength far exceeds the demands of hiking, it can be used to attach water bottles or gear to the outside of a backpack, or as a convenient connector when setting up tarps and tents.
