A rockwall climber uses the ABIS system

The ABIS-Braking system allows personnel to quickly attach to and detach from a standard 2-point harness, rappel while controlling their speed of descent, and stop at any point during descent
using a brake. A tipping restraint system additionally allows the user to adjust their angle relative to the rope to maintain an ergonomically sound position, perform maintenance mid-descent, and
compensate for heavy backpacks or other loads.

The braking system improves safety and eliminates the need for leather gloves, which typically wear through during extended or repeated fast-roping. Because the brake can be operated with one hand, the other hand is free to perform other functions during descent.
