Assisted braking or none?
- Manual (also called tubular or tube-style) devices do not provide any assisted braking
- Simple, lightweight design; easy to use
- Work with many rope diameters and can accommodate single or double ropes
- Some find them slow for rappelling
- Assisted braking devices are designed to lock down on the rope when a sudden force is applied
- One type relies on its design or geometry to provide braking assistance
- Another type uses an internal mechanical camming mechanism to help lock the rope when a fall happens; these are heavier and designed for single ropes
Other considerations
- Suitable for rappelling: Many belay devices also double as a tool for rappelling during descents
- Fits rope size: Consider the thickness of the rope you're using and make sure it fits
