What Are the Different Types of Carabiners? (Complete Breakdown)

Carabiners are essential tools for climbers, hikers, and outdoor enthusiasts, but not all carabiners are created equal. Understanding the different types will help you choose the right one for your specific needs while ensuring maximum safety.

1. By Gate Mechanism

• Non-locking Carabiners: Feature spring-loaded gates (straight or wire) for quick clipping
• Locking Carabiners: Include screwgate, twistlock, and auto-locking designs for critical connections
• Wire Gate: Lightweight option that resists freezing in cold conditions

2. By Shape

• D-Shaped: Strongest design for climbing, with optimal weight distribution
• Oval: Symmetrical shape ideal for gear organization
• Pear (HMS): Large, pear-shaped opening perfect for belaying
• Asymmetric D: Hybrid between D and oval shapes

3. By Material

• Aluminum: Lightweight (ideal for climbing) with 20-30kN strength
• Steel: Heavier but more durable (30-50kN) for industrial use
• Titanium: Premium option combining strength and lightness

4. Specialized Types

• Quickdraw Carabiners: Pre-assembled pairs for sport climbing
• Pulley Carabiners: Designed for rescue systems
• Keychain Carabiners: Small, non-load-bearing versions for everyday use

Each type has specific safety ratings (measured in kN) and intended uses. Always check for UIAA/CE certification for climbing applications, and match the carabiner to your specific activity. Remember that proper maintenance and regular inspection are just as important as selecting the right type.
