COBRA // DYNAMIC NON-INVASIVE // Tree Cable
Several reasons exist for cabling, two primary reasons are of greatest concern to arborists: Repairing damage after failure and installing supplemental support to avoid failure. The latter issue is what inspired the development of dynam- ic cabling systems.
The dynamic, low-tension support of Cobra systems is designed to work with the tree’s natural and growing defenses, unlike certain static instal- lations that have no “give” and become a crutch.
For more information on Cobra, look Sherrill- tree.com up on the website and search the words “Cobra tree cabling”.

COBRA // SYSTEMS
Think back for a moment to the first time you "really paid attention" to a mature tree flailing in strong, gusting wind. Were you not shocked at the amount of movement and how all parts were acting independently to discharge the force? This is why Cobra was designed, not simply
to hold two parts of a tree together on a calm sunny day, but to keep those parts from reaching their failure point when whipped and twisted by mother nature.
Each case of Cobra comes with the following items:
• Cobra rope
• Anti-abrasion hose
• Expansion inserts
• Shock absorbers
• End caps (color coded to the year)
• Torch
• See charts on this page for the specific list of Cobra items in each case.
