Professional Heavy Duty Locking Carabiner for Outdoor Activities

Overview

Constructed from cold-forged stainless steel and featuring a triple-locking mechanism, it sets the standard for reliability in applications where failure is not an option from big-wall climbing expeditions to offshore rig maintenance.

Features

Extreme Load-Bearing Capability

35kN Tensile Rating: Engineered to handle dynamic shock loads (22kN impact resistance), surpassing the 25kN UIAA standard for climbing carabiners with a safety factor of 7:1 (35kN / 5,000lbs working load).

Stainless Steel Superiority: Cold-forged 17-4 PH stainless steel (H900 temper) offers a yield strength of 1,034 MPa and a salt spray resistance of 1,500 hours (ASTM B117)—4x longer than aluminum making it ideal for offshore and marine environments.

Military-Grade Locking System

Triple-Layer Security:

Spring-Loaded Auto-Lock (5N activation force) engages instantly upon gate closure.

Threaded Collar (1.2mm pitch, 360° rotation) provides secondary mechanical lock, verified to withstand 1,000 hours of vibration at 15G without loosening.

Anti-Rotation Tab prevents gate misalignment, ensuring consistent load path under lateral forces.

Magnetic Gate Detent: A 0.5N rare-earth magnet holds the gate closed during transport, reducing the risk of accidental opening in high-vibration scenarios (e.g., helicopter transport, machinery operation).

Heavy-Duty Ergonomics

Reinforced Elliptical Spine: 10mm thick cross-section (110x75mm) with a 20° load-bearing angle distributes stress evenly, reducing rope wear by 30% compared to standard D-shaped carabiners.

Induction-Hardened Contact Points: Nose (50HRC) and gate edges (45HRC) undergo induction heating to enhance surface hardness, extending wear life in high-friction applications (e.g., big-wall aid climbing) by 50%.

Precision Manufacturing

Laser-Calibrated Tolerances: Gate gap maintained at 11.5±0.1mm using CNC machining, ensuring consistent fit with 10-13mm ropes and minimizing lateral play (<0.3mm) under load.

Traceability System: Each carabiner carries a unique 12-digit serial number linked to its heat treatment batch and test results, compliant with ISO 9001:2015 traceability requirements.

Application

Professional Climbing: Trusted by big-wall climbers (El Capitan ascents), ice climbers (vertical ice fields), and mountaineers for critical placements, meeting the rigorous UIAA 124 Type C certification for carabiners used in fall arrest.

Industrial Rope Access: Essential for wind turbine technicians (ANSI Z359.12 compliant), high-rise window washers, and nuclear facility inspectors, where a 7:1 safety factor provides maximum margin for error.

Search & Rescue: Used in technical rescue systems (NFPA 1983 compliant) for lowering victims, setting up litter carries, and creating anchor points in unstable terrain, with a corrosion resistance that withstands mountain stream and saltwater exposure.

Why Choose Us

Triple Certification Excellence: The only carabiner to hold UIAA 124 (Type C), EN 362, and NFPA 1983 certifications, making it suitable for the most regulated industries.

Rust-Proof PVD Coating: Black physical vapor deposition (PVD) coating (5μm thickness) bonds at the molecular level, passing 1,500-hour salt spray testing with zero corrosion critical for maritime and polar applications.

Engineer-Collaborated Design: Developed in partnership with IRATA-certified rope access professionals, featuring a 15° gate angle that optimizes one-handed operation while wearing cut-resistant gloves.
