Additional protection for via ferrata
for extremely difficult, vertical or overhanging sections of via ferrata, using
sewn slings and the FB-sling friction knot by Franz Bachmann, which provides
sufficient friction even on steel wire.
The application of the FB-sling friction knot on via ferrata was guided by the
request for maximum simplicity and minimal additional gear requirements.
Via ferrata protection with FB-sling friction knot
- Tied with a two-foot long, 20mm sewn sling. Tie an overhand knot
as close to the sewn junction as possible.
- Wrap three times around the steel wire as shown.
- Add a full downward wrap, thread through the loop. Tie another
sewn sling to the harness, using a girth hitch, and chain both links
using a locking biner. Add overhand knots to the second sling to
adjust the length. The distance between the knot and the harness
should be approximately three feet.
Use of the additional protection
The application of the FB-sling friction knot is an additional protection only,
and cannot replace the use of a proper via ferrata protection. It must only be
used in combination.
