4.3.3 "Mammut S+" roof hooks
"Mammut S+" roof hooks are used to ensure the safety of the structure under high
snow loads. This roof hook provides improved static characteristics compared with
the "Standard S+" roof hook. In certain conditions (e.g. low snow load zone), it may
be possible to install "Mammut S+" roof hooks only on every second rafter and
consequently reduce the number of roof hooks.
