EJECT and NAJA can be used on a single rope (SRT/SRS) with a stopper knot.

Moving within the tree with two anchors Using two systems simultaneously on two separate anchors provides optimal balance while cutting and facilitates movement.

Movement Within the Tree

EJECT and NAJA are used here on doubled rope (DdRT/MRS), but may also be used on single rope (SRT/SRS) with a stopper knot.

Single rope ascent technique The access rope is attached to the base of the tree and runs through an appropriate anchor in the tree. It will also be used for work. On a single rope, the ZIGZAG must only be used with the CHICANE.

This technique allows for rapid rescue and efficient climbing with the KNEE ASCENT knee ascender.

Tree Access

Doubled rope ascent technique The arborist ascends the access rope (purple).

In the event of a problem, such as a hornet attack, they can self-evacuate with the work rope (blue). A mule knot or releasable knot secures the ZIGZAG.

This versatile ascent technique is adaptable to many situations and allows an access rope to be available during work.
