Vertical caving terminology and methods > SRT basic terms
An extra long rebelay loop used at a rebelay, or just before a traverse line, or connecting to an anchor at the end of a rope, where a pendulum is required. This is made long enough that a caver can abseil down slightly below the level of the anchor, lock off their descender, and then pull themselves over to it using the down rope, such that they end up at the anchor itself. When prusiking past that point, the pendulum loop is slowly paid out after starting to prusik on the up rope, until hanging vertically. (In Australia, a series of pendulum loops used in a row to try to diagonally cross a wall, is sometimes called a tension traverse, but a tension traverse is something different in Britain.)
