Cobra Tree Support System- A No Drill Method

Every Tree Needs A Caretaker!

At Skyline Tree Service, we provide professional installation of the Cobra Tree Support System, a non-invasive cabling solution designed to support structurally compromised trees while allowing for natural movement and growth. Unlike traditional steel cables, the Cobra system is made from high-quality, UV-resistant synthetic fiber, offering flexibility, longevity, and improved tree health.


Why Choose the Cobra System?

Over time, trees can develop structural weaknesses due to storms, excessive weight, poor branch attachments, or natural defects. The Cobra system helps reduce the risk of limb or trunk failure by stabilizing weak areas while still permitting natural sway. This movement promotes stronger wood development and minimizes stress on the tree.

It’s important to note that no support system can guarantee a tree will not fail. Under extreme conditions, all trees are susceptible to failure regardless of their size or the support in place. However, when properly installed and maintained, the Cobra system significantly reduces risk and improves tree longevity.



Dynamic vs. Static Installation

The Cobra system can be installed as either a dynamic or static support system, depending on the tree’s structural defect:

  • Dynamic Installation (with Shock Absorber): Used for branch defects where controlled movement is beneficial, allowing the tree to strengthen over time while still receiving critical support.
  • Static Installation (without Shock Absorber): Recommended for structural issues such as cracks or splits in unions, where minimal movement is necessary to prevent further damage.

Our certified arborists will assess the defect and determine the best installation method to provide optimal safety and longevity for your tree.





Our Installation Process

Comprehensive Assessment – We evaluate the tree’s structure, health, and risk factors.
Customized Installation – The appropriate Cobra system is selected and installed securely without drilling into the tree.
Optimal Placement – Cabling is installed at approximately two-thirds of the tree’s height to provide maximum support while allowing for natural movement.
Maintenance Recommendations – We provide guidance on ongoing inspections to ensure long-term effectiveness. Inspection intervals are 3 years.


Cobra System Sizes

We offer four sizes of the Cobra system to accommodate different tree sizes and structural needs:

  • Cobra Mini – A lightweight option for small trees or branches needing minimal support up to 6” in diameter.
  • Cobra 2t – Ideal for small to medium trees with minor structural concerns up to 16” in diameter.
  • Cobra 4t – Suited for medium to large trees requiring moderate support between 16-24” in diameter.
  • Cobra 8t – Designed for large trees or significant structural weaknesses between 24-32” in diameter.
