Step 4 to Rig Carabiner Brake
Use locking carabiners so the brake crabs never come open by accident.

Step 4

Now for the most important step to rig your carabiner brake system. Take two more carabiners and clip them across the carabiner frame and below the bight of rope. Make sure the carabiners both face down and away from the rope and are reversed to each other with each carabiner gate opposed to the other. Use locking carabiners if possible to avoid any possibility of the gates accidently coming open. Pull down on the bight of rope and let it run across the top of the carabiners. Add additional carabiners or another frame of two carabiners and two more brake carabiners on the end to create even more friction in the system.

Ready to Rappel!

Now you’re ready to rappel. But first, double-check your whole carabiner brake system. Make sure all carabiners are reversed to each other and all gates are opposed. This rappel system builds up lots of heat while rappelling. The brake and frame carabiners might be too hot to handle when you reach your next rappel station or the ground.
