Ask the Route Setters: What Are Volumes?
Jan 22, 2015
They’re called Volumes – aptly so, as they add volume to the walls. If a piece of tape is added to the side of the volume, then the ENTIRE block, including all the holds on ’em, is game for you to use.
Exception: if a particular hold is taped on the volume, then it is only that hold you may use.
Go forth, young Jedi.
