It is recommended to use an HMS Bruce Steel FG, HMS Strike FG or
HMS Strike Slider FG carabiner. If you opt for another
carabiner, make sure to use one with an HMS locking mechanism (pear-
shaped), with anti-torsion, if possible, and make sure that
the belaying device is in contact with the large side of the carabiner. A
straight/pointed carabiner in contact with the belaying device can hinder braking
