Friction Hitches and Termination Knots
The following knots were evaluated to determine their characteristics when placed in a fall
situation. The performance measures for fall arrestors found in CSA Standard Z259.2 Fall Arresting
Devices, Personnel Lowering Devices and Vertical Life Lines were used as a guideline for the testing.
Further information and testing information can be requested from the Arborist Safe Work Practices
Committee Chair. The Arborist Safe Work Practices Committee urges users to use the following knots
in their fall protection systems.
All knots and friction hitches must be tied, dressed and set properly. Repetitive loading and unloading
of knots can potentially slacken off the knot. Therefore, all knots must be monitored throughout the
climbing process.
