Help Prevent Failure
Cabling involves the installation of either steel cables or synthetic rope systems into the crown of the tree. These cables are installed between the major limbs that have been identified as potentially weak to help support the poor branch unions. Cables can also help reduce the potential damage incurred during high winds and snow, even if a structural defect has not been identified, simply by adding support.
Bolting involves drilling through the crotch of the tree that has been identified as weak, and installing a metal rod with nuts and washers on each end. This process is used in conjunction with cable installation.
