How many pounds can a carabiner hold？
Many of our customers, when inquiring about quotes, ask how many pounds a carabiner can hold. The answer depends not only on its size. Its weight-bearing capacity depends on the material, intended use, design, and manufacturing process.
So, let’s discuss aluminum alloy carabiners in detail：
The most commonly used material is aluminum alloy. For everyday accessories like keychains, pet leashes, and backpack hooks, 6061 and 6063 aluminum alloys are widely used. They are lightweight and corrosion-resistant, with a breaking strength typically between 4 and 6 kg. These aluminum alloys are safe for non-load-bearing applications, but are not suitable for rock climbing and mountaineering.
For outdoor rock climbing and high-load-bearing applications, 7075 aluminum alloy is preferred due to its higher strength. These carabiners can withstand loads of 20 to 30 kN, equivalent to 4,500 to 6,800 pounds.
Stainless steel carabiners are heavier, but are often used in industrial or marine environments, where resistance to wear and corrosion is more important than weight.
So how do you choose?
- Outdoor product companies: Choose high-strength hanging tools to ensure secure mounting for camping and outdoor accessories.
- High-load capacity & rock climbing: Choose 7075 carabiners with a load capacity of 20-30 kN, suitable for applications requiring high loads.
- Pet brands: 6061/6063 are more suitable, as they offer adequate medium tensile strength, are lightweight, and come in a variety of colors.
- Fashion promotional gifts: Focus on appearance, craftsmanship, and custom logos, rather than excessive load capacity.
- Industrial customers: They tend to choose stainless steel or large 7075 carabiners with a load capacity of 25 kN or higher.
A carabiner is more than just a piece of hardware; it’s the bond between the product and the end user. Therefore, choosing the right carabiner for the specific situation is crucial.
When choosing a carabiner, consider not only the load capacity but also the product’s application. If you’re considering the right carabiner for your product brand, please let us know your target market and application scenarios.
We can recommend the most suitable material, structure, and load-bearing capacity based on your brand goals, and even provide customizable carabiners. We can help you bring reliable, tailored products to market.
How many pounds can a carabiner hold？
1 kN ≈ 225 pounds.
👉 Calculation:
1 N ≈ 0.22481 lbf
So 1 kN = 1000 N × 0.22481 ≈ 224.81 lbf
