Vertical caving terminology and methods > Rigging methods and equipment
Literally what it says. This is a metal bar that would normally be used in scaffolding, which is fixed across a passage or pitch, which can be used as an anchor. These are often cemented into place at the entrance to a pothole, and are generally treated as if they are as good as, or sometimes better than, a standard anchor. They are often used without a second attachment point, sometimes with a backup, so there is no Y-hang.
