What have we learned about energy absorption when it comes to dynamic activities that test the limits of ropes and wood? For one, we’ve learned that tensile strength alone is not all it’s cracked up to be. For example, no one needs to spell out the result of bungee jumping using high-strength cable instead of (significantly weaker) elastic rope.
Although an extreme example, the physics are virtually identical when arresting other falling loads, including tree parts. No, not because the load shouldn’t be injured, rather to lessen forces capable of cracking an anchor point or snapping high-strength ropes. Not only are such shattering forces the inspiration for modern tree cabling systems like Cobra and TreeSave, but they are also the rea- son many arborists are choosing Dynasorb II for wood-dropping activities, too.
• 1/2" = 10,500 lbs tensile
• 9/16" =13,200 lbs tensile
• 5/8" = 16,300 lbs tensile
• 3/4" = Tensile Strength is Average Break Strength with a splice
• Limited U.S. availabilty

WORKS WELL WITH
NOTCH BACK BONE
The Notch BackBone makes more efficient rigging possible, as a quick connection be- tween your spliced rigging line and slings. Perfect for top-down rigging, as well as single, double, or even triple limb lowering. You can also use the BackBone to create a balancer for precision lifting and lowering. Go to page 114 for more information.
