| Overview: |
A rappel device simply creates friction between the rope and the device to help slow and control a descent. When possible, try and use a single tool for both rappelling and belaying. This saves weight and prevents gear excess.

Plate belay devices
Most belay devices can be used for rappelling. Before using them, however, determine whether belay devices are suited for rappelling. Some devices have very low friction and the configuration may need to be adjusted (e.g. adding more carabiners, changing configuration) before they provide an adequate rappel system. Also, check manufacturer’s recommendations. |

Figure 8
Figure eights are a traditional rappel device, well suited to most situations. There are several variations of the standard shape available which are not differentiated in this discussion.
NOTE: Rope can flip over the end of the figure 8 and create a girth hitch that locks up the system. This is especially a concern on rappels that go over edges or overhangs and the device is extended from the harness. |

Carabiner brake and Italian hitch
The carabiner brake consists of an extension and a cage which consist of interlocking reversed and opposed carabiners or single locking carabiners and brakebars. The carabiner brake is a reasonable alternative if other devices are not available. Additional “brake bar” carabiners can be added if more friction is required (e.g. when rappelling on small diameter ropes).
Italian hitch
The Italian hitch can be used as a rappel device.
The Italian hitch will create serious twists in the rope when rappelling. |
