Usage
The Valdotain Tresse (VT) is a directional friction hitch that is popular with arborists. It is used to attach a carabiner to a rope, allowing a climber to ascend or descend.
Warning
Verify tying technique with a skilled instructor where knot failure could cause property damage, injury, or death.
Also known as
- VT
- Vallard Tresse
- Valdôtain Tresse
Structure
The cord wrapped around the main line is often referred to as a "spliced eye, split tail friction cord" and has permanently sewn or spliced loops at each end. In absence of this specialty cord, a pair of
Double Overhand Noose knots is sometimes used.
Strength/Reliability
A climber may have to experiment with different types, lengths, and diameters of the split-tail in order for the Valdotain tresse to be effective. For example, if the split-tail is too long, the hitch may not grip immediately when it is pulled down.
