Key features

This auto-locking carabiner prevents accidental gate opening under load, solving the risk of unclipping during climbs or High-altitude operations.

Its dual-action locking mechanism ensures secure attachment, rated for 35kN strength - ideal for rock climbing, via ferrata, or industrial fall protection.

Crafted from aerospace-grade aluminum, it offers high strength-to-weight ratio without rusting.

Unlike steel hooks, it reduces gear fatigue during long ascents or descents, making it perfect for alpine climbing, caving, or rescue operations where every gram counts.

The textured gate and wide opening allow easy clipping even with thick gloves, improving efficiency in cold or wet conditions.

Suitable for harnesses, lanyards, or anchor systems, it enhances safety and speed during critical maneuvers, reducing user error in high-stress environments.

Product Q&A

Q:What is the weight limit of this auto-lock carabiner?

This carabiner is rated for a minimum breaking strength of 35kN (approx. 7,800 lbs) along the major axis. Always adhere to the manufacturer's specified working load limit for safety in climbing or rigging applications.

Q:Is this carabiner suitable for lead climbing or belaying?

Yes, its auto-locking gate and high strength rating make it ideal for belaying, rappelling, and as a master point connector. Ensure it is UIAA or CE certified for life-support activities before use in critical climbing scenarios.

Q:How do I operate the auto-locking mechanism?

To open, slide the sleeve down and pull the gate; to lock, release the gate and slide the sleeve up until it clicks. This dual-action design prevents accidental opening from rock contact or vibration during use.

Q:Can I use this carabiner in wet or salty environments?

Yes, the 7075 aluminum alloy is anodized for corrosion resistance, making it suitable for coastal climbing or via ferrata. Rinse with fresh water after exposure to saltwater to maintain longevity and smooth gate operation.
