Kiwi coil is a technique used to bring a rope to shorten the distance between two climbers. This technique is usually used for simultaneous climbing on easy terrain or glacier trips.
See below how to do this:
One of the things you should be very careful about is using the kiwi coil on the refrigerator. It is important to add an extra element to tie the rope. The climber must tie an intact knot in the line and attach it to the carabiner. The reason for this is to ensure that if your partner is in a rut and you have to open the kiwi, you will not suffocate when you open it.
