Cabling and Bracing

We normally use steel through-hardware and Treesave Brand elastic rope cable. http://www.sherrilltree.com/ for more information.

cable sizes:  
10 mm cable 5,000 lb breaking strength
13 mm cable 11,000 lb breaking strength
10 mm spectra cable 20,000 lb. breaking strength

Traditional steel cable is thought to have the following problems:

  1. Fixing trunks rigidly to one another reduces the tree’s ability to dissipate high wind forces through deflection of the crown. Also, high wind conditions can create slack in the cable which, when suddenly taken up can result in failure of the cable or of the trunks above the cable.
  2. The supported parts of the tree come to rely on the cable’s support. Should the cable break the tree might be less able to hold itself together than before the cable was installed.
