BELAYING AND RAPPELLING
Attach all belay and rappel devices to the belay loop with
a locking carabiner (Figure 4). The belay loop is engineered
for extreme structural strength (>15kN/3350 lbf), equal to
the main harness structure, and when used correctly for
belaying and rappelling provides a safer two-point load.
Do not employ any attachment system that causes undue
direct friction to the belay loop or either of the tie-in points.
Figure 4
Never girth hitch anything to your belay loop. This can focus
abrasion in a single location. Before use, always inspect the
belay loop for signs of wear or damage, see: "Inspection".
The belay loop is to be used as the attachment point in any
rescue situation.
