ATRAES in association with Into Trees Joe Harris and Angus McMahon of Shebrooke Tree Services have produced lesson number two in a series on SRT Ascent.
In this video Joe talks about 'double-bagging' when isolating the anchor point and looks at various ways to tie off the access line once installed.
As with all things on the net, this video should not be your only source of knowledge - if you are not sure what Joe is talking about seek further training with an appropriate provider.
