Rappel Devices (Descenders, Belay Devices)

Description

A rappel device is used to convey a person from the top to the bottom. The rappel device is almost always attached to the harness of the person rappelling, although sometimes it is attached to the harness of the belayer, who lowers the rappeller down. The decision of which rappel device to use is generally based on:

• The type of activity
• The amount of friction you need
• What's available
• Your knowledge and experience
• Your personal preference
• Cost
