Do you think the carabiner is durable enough to withstand heavy loads?
Imran Hanafiah –
Thank you for reaching out about the Problue AC-30-12 Heavy Duty Shock Line. Our carabiners are designed to be durable and long-lasting, and they’ve been tested with heavy loads in mind. The stainless steel construction, in particular, provides excellent resistance to rust and corrosion. While every item may have its own unique characteristics, we’re confident that the Problue AC-30-12 carabiner can withstand heavy loads. However, we recommend checking the manufacturer’s specifications and instructions for more information. Would you like to share more about your experience with the product?

What’s the difference between the Problue AC-30-12 Heavy Duty Shock Line and the AC-20-10 model, do they have any significant upgrades?
Imran Hanafiah –
Thank you for your question, Ramesh. The main difference between our Problue AC-30-12 Heavy Duty Shock Line and the AC-20-10 model is the breaking strength and durability. The AC-30-12 has a higher breaking strength of 3,000 pounds, whereas the AC-20-10 has a breaking strength of 2,000 pounds. Additionally, the AC-30-12 features a wire interior for improved resistance to abrasion. Both lines come with double end stainless steel carabiners, but the AC-30-12’s carabiners are rated for heavier loads. If you have any further questions, please don’t hesitate to ask.
