Sender Screwgate Carabiner

A screwgate carabiner features a screw mechanism on the gate that locks it in place, preventing accidental openings. This added security makes it an excellent choice for climbing, as it ensures that your gear stays securely attached, reducing the risk of accidents.

The Keylock Nose design eliminates the hook or notch typically found on carabiners, which can snag on ropes and gear. This means you can clip and unclipping more smoothly and safely, allowing for a more efficient climbing experience without interruptions.

Major Axis Strength refers to the maximum force (measured in kilonewtons, kN) that a carabiner can withstand when the load is applied along its strongest axis. Understanding this strength is crucial for climbers, as it indicates how much weight the carabiner can safely hold during climbing activities.

Minor Axis Strength measures the carabiner's strength when the load is applied along its weaker axis. While this strength is typically lower than the major axis strength, knowing it helps climbers understand the limits of the carabiner's performance in different orientations, ensuring safer climbing practices.

Open Gate Strength indicates the amount of force a carabiner can withstand when its gate is open. This is crucial for safety, as it shows how much weight the carabiner can handle if it accidentally opens while in use. A higher open gate strength means a more reliable and safer carabiner for your climbing adventures.

To determine if a carabiner is suitable for your climbing needs, consider its major and minor axis strengths, open gate strength, and whether it features a screwgate or keylock design. Ensure that the specifications meet or exceed the requirements for the type of climbing you plan to do, whether it's sport climbing, trad climbing, or mountaineering.
