Introduction to carabiners
This is a short introduction to carabiners, along with their use and costs
What are carabiners?
A carabiner is a strong oval or D-shaped loop or hoop. It has a gate which you can open in order to connect it to, and disconnect it from, safety ropes. The gate is almost always spring loaded, and it also has a nut which screws into place when the gate is closed to ensure that it will not open by accident.
How strong are they?
Because carabiners are part of a safety setup, they need to be very strong. Strength ratings vary, and are measured in KN which stands for kilonewtons. This is actually a measurement of the force they can withstand, because they are designed to stop falling objects which create much more force that a simple hanging weight. A typical climbing carabiner could have something like a 24KN rating.
What can carabiners be used for?
They can be used in various rope-based activities, such as climbing, caving, and abseiling.
How much do they cost?
Climbing carabiners cost aroud £5-10 each.
What else do you need for climbing?
Apart from carabiners, as a minimum you will also need climbing shoes, a helmet, a belay device, ropes, and a harness.
