When installed properly in your trees, steel cable and brace rods can strengthen a structurally weak tree and significantly reduce the risk of failure. A typical static cabling system consists of a single EHS (extra high strength) steel cable attached to eye bolts or wire stops in the upper one-third of the tree. A support cable is usually installed between two codominant leaders that have a weak union that would likely fail if subjected to high winds. Braces are threaded rods that are installed directly through the weak union to provide additional support. Steel cabling and bracing requires drilling a hole into the sound wood to maximize support strength.
Dynamic Cabling Support System
There are alternatives to steel static support systems. Cobra® support systems consist of a poly-propylene hollow braid rope and an inline shock absorber that requires no drilling and allows the tree to sway more naturally in light winds. This is important because trees will grow differently depending on the characteristics of the system installed. Streamline arborists have the skill and experience to determine if your trees need structural support, and if so, which system would provide the best results.
