A training reference on single rope technique for working arborists.
Best Practices for SRT in Arboriculture is a training reference on single rope technique (SRT) for tree climbers. It helps climbers moving from doubled-rope systems understand anchors, devices and safe habits for working on a stationary rope.
Single rope technique has changed how many arborists climb. Ascending a fixed line is faster and less tiring than body-thrusting on a doubled rope, and a stationary rope system can be set from the ground with a throw line. It also brings new risks: anchor forces, base-tie choices and device selection all matter more.
A focused guide helps climbers understand the reasoning behind SRS setups, not just the steps, so they can make good choices in trees that do not match the textbook.
Single rope technique has also brought a wave of new devices, from rope wrenches to mechanical friction devices and multi-function ascenders. A best-practices guide helps you judge new gear by the same principles: secure anchors, appropriate devices for the rope, backups where needed, and a rescue plan before anyone leaves the ground. That habit matters more than any single product.
Use the book alongside hands-on training with a qualified climber. Practice every system low and slow before working at height, follow ANSI Z133 and device makers' instructions, and inspect your gear before each climb.
It makes a good reference for crew training sessions and for climbers preparing for certification. Browse more books and training materials.
Revisit it each season as your systems change.
