Throwline


The Throwline is a timed event that tests the competitors' ability to accurately place a climbing line in a tree at heights of up to 60 feet. The competitor attempts to toss a line through two of eight targets. Each target is worth a different amount of points depending on difficulty.

A throwline is used for climbers to set their climing line into a tree. A rope must be set and a climbing line installed in order for a tree worker to ascend a tree to perform tree work. Throwlines must be installed at a point that will be sturdy and secure to accommodate the climbers's weight with gear while working in the tree.
