Volumes

Volumes are an extremely large type of hold that any variety of holds can be attached to. The volume is attached to the wall, and it has pre-placed t-nuts in it to which other holds can be attached. Volumes were at one time prevalent in Europe and on the World Cup circuit, but are now used world wide to make the climbing more 3-dimensional and, since they have a wider usable area, less susceptible for size / span dis- advantages.
