Page 136 - Rappelling

To rig a tether/rappel extension with a sling, start with a double-length (48-inch) sling and girth-hitch
it through both tie-in points on the harness. Tie an overhand knot about halfway down the length of
the sling, adjusting the knot so that when you clip it back into the harness belay loop with a locking
carabiner, the length to the overhand knot is equalized. Clipping the locking carabiner of your rappel
device into both of the loops you’ve created in the sling makes the sling itself redundant when it’s
clipped back into the harness belay loop.
