How to Choose Climbing Carabiners?

Starting a climbing adventure requires more than just skill; it demands the right gear. The carabiner is a critical component that ensures your safety. This guide, written by NAL HON Industrial, will give you the knowledge to decide when selecting a suitable climbing carabiner. It covers everything you should know to choose the best carabiner for your climbing needs.

What is a Climbing Carabiner?

A climbing carabiner is a metal loop with a spring-loaded gate connecting different climber's gear components. It is crucial in ensuring safety and reliability while climbing and is used to attach a climber to a rope, connect different pieces of protection, or secure other accessories. Carabiners are used in climbing, sailing, and rescue operations. They are commonly constructed using steel alloy, stainless steel, or aluminum alloy materials.

Types of Climbing Carabiners

Knowing the different types of carabiners is crucial for climbers to choose the appropriate tool for each use, guaranteeing a secure and effective climbing experience.

1. Categorized by Material

• Steel Alloy:

  Steel is strong and durable but heavy compared to aluminum. It can withstand tension, compression, and bending. However, it may corrode in certain environments and require special treatments to enhance its corrosion resistance.

• Aluminum Alloy:

  Aluminum carabiners are lighter and resistant to corrosion. Though weaker than steel, they still provide sufficient strength for general climbing use.

• Stainless Steel:

  Due to the presence of chromium, stainless steel is known for its excellent corrosion resistance. It is strong, durable, and performs well at high temperatures. However, it is heavier and more expensive than aluminum.

2. Categorized by Shapes

• Oval Shape

  Oval-shaped carabiners possess a symmetrical form that maintains a consistent curve. Thanks to their user-friendly design, they provide easy clipping and unclipping. Oval carabiners are a common choice for aid climbing, where versatility and ease of handling are fundamental. They also prove useful in various hauling systems.

• D Shape

  D-shaped carabiners are characterized by a curved spine and a straight gate side, resembling the letter "D." This design focuses the load along the spine, enhancing strength. Widely used in various climbing scenarios, D-shaped carabiners are especially popular for connecting devices to a harness. Their ergonomic shape minimizes weight without compromising strength.

• Offset D Shape

  Offset D carabiners offer a larger gate opening while maintaining the advantages of the classic D shape. They are valuable when clipping multiple items or dealing with bulky gear and offer versatility and ease of use.

• HMS (Henry Munter System carabiner)

  HMS carabiners, also called pear-shaped carabiners or pearabiners, are distinctive with a pear-shaped or slightly offset D shape, often featuring a larger gate opening. This design accommodates the hitching of multiple ropes or devices. Commonly used in belay and rigging systems, HMS carabiners excel in accommodating a Munter hitch for belaying, making them a popular choice for multi-pitch climbing and rappelling.

3. Categorized by Gate Types

• Straight

Straight gate carabiners are quick and easy to clip, making them ideal for rapid and unclipping scenarios. They are often used for quick draws and clipping protection into bolts or gear placements.

• Bent

  Bent gate carabiners have a curved gate for smoother and more secure clipping. They also provide a larger opening for easier rope insertion. They are often used at the rope-clipping end of quickdraws.

• Wiregate

  Wiregate carabiners are a lightweight and preferred option in alpine and trad climbing. They replace the solid gate with a loop of wire, reducing the risk of gate flutter and freezing in cold conditions during falls.

• Locking Gate: Further divided into Screw-lock and Auto-lock.

  Locking carabiners enhance safety in scenarios where security is paramount. They are crucial for anchoring and belaying, especially when the carabiner must remain securely closed, such as anchors, belay systems, and rappelling.

• Screw-lock: Requires manual screwing and unscrewing of the gate, offering a reliable and secure closure.

• Auto-lock: This type utilizes an automatic closing mechanism that engages when the gate is closed, including twist lock and triple lock. It provides an additional layer of safety by reducing the risk of human error.

7 Factors to Consider When Purchasing a Climbing Carabiner

1. Load Capacity

The load capacity is typically measured in kilonewtons (kN) and varies based on the direction of the load. When choosing a carabiner for climbing, check its Major Axis and Minor Axis strength ratings. The Major Axis strength handles the force applied parallel to its spine, while the Minor Axis strength handles the force applied perpendicular to the spine. Always choose a carabiner that can support the expected loads during climbing.

2. Gate Type

The gate type of a climbing carabiner affects ease of use and security. Evaluate straight, bent, wiregate, and locking gates based on factors such as ease of clipping, safety, and compatibility with your climbing equipment.

3. Material

When choosing a climbing carabiner, consider the material's weight, durability, and corrosion resistance. Common materials include steel alloy, aluminum alloy, and stainless steel.

4. Weight

When selecting a climbing carabiner, prioritize functionality over weight. Lightweight carabiners are preferred for alpine climbing and long routes, but their strength and durability should not be compromised. The lightest options may be small, making it difficult to grip ropes or bolts. Due to narrower gate bars, they may also have lower gate-open strength and a shorter lifespan.

5. Quality and Certification

To ensure safety, choose only certified carabiners from trustworthy organizations like the UIAA, CE, or ENs. Avoid uncertified carabiners.

6. Size

Consider the size of the carabiner's gate opening to ensure compatibility with your climbing gear. A larger gate opening facilitates easier clipping and unclipping, especially when wearing gloves or dealing with thicker ropes.

7. Cost

When buying climbing carabiners, set a budget and choose options that offer the best value. Consider factors such as material, certification, and features. Quality carabiners are essential for safety during climbing activities.

Maintenance and Safety Precautions for Climbing Carabiners

1. Safety Precautions During Use:

• Check Equipment Condition: Inspect the carabiner before use for any damages or deformations.

• Correct Usage: Always fully close the carabiner gate to ensure climbing safety.

• Understand Load Limits: Don't exceed the carabiner's load limit for safe use.

• Proper Storage: Store climbing carabiners in a cool, dry place to avoid damage from prolonged exposure to sunlight, rain, or humidity.

2. Regular Inspection and Proper Maintenance Methods:

• Regular: Inspection: Inspect the climbing carabiner regularly, including mechanisms, gate, and locking mechanism (if applicable).

• Cleaning: Clean your climbing carabiners regularly with mild soap and water to remove dirt, grime, and debris. Avoid using harsh chemicals or solvents that may damage the carabiner's materials.

• Lubrication: To ensure smooth operation, lubricate the carabiner's moving parts with a compatible lubricant that does not attract dirt or dust.

• Follow Manufacturer Guidelines: Follow the manufacturer's guidelines for climbing carabiners' use, care, and maintenance to ensure the equipment's safety and longevity.

3. Replacement Criteria:

• Visible Damage: Inspect your climbing carabiners regularly for any signs of visible damage, such as cracks, dents, or deformation. If you notice any significant damage that compromises the structural integrity of the carabiner, it should be replaced immediately.

• Wear and Tear: Watch for wear on your climbing carabiners, especially the contact surfaces and gate mechanism. Replace if excessively worn or damaged.

• Exceeding Lifespan: According to the manufacturer's guidelines, periodic replacements should be considered even if the carabiner appears in good condition.

• Extreme Loads: Inspect climbing carabiners after extreme loads or falls. Replace them if they show signs of stress or deformation.

• Corrosion and Rust: Check climbing carabiners for rust or corrosion regularly. Replace damaged ones to stay safe.

• Gate Functionality: Regularly test your carabiner's gate for smooth and secure functionality. Replace any malfunctioning carabiners to prevent gate failure.

Regular maintenance and safety training is important for safely using climbing carabiners.
