The Case for Dynamic Limb Restraint Systems

It is determined that the tree has a weakness in it. Take it down? Or provide some assistance to it and extend the life and beauty of the tree?

The Guardian offers these advantages and benefits:

  • Dynamic, supplemental support allows the tree to sway naturally, building its own tissue to strengthen itself.
  • No drilling; no wounds to the tree.
  • Installation is faster, simpler, easier than steel.
  • Convenient, lightweight materials.
  • Fewer tools required than steel (only a splicing tool and a scissors).
  • Fewer parts to inventory (3/4" or 3/8" rope and the protective shield).
  • UV stabilized fibers maintain strength and longevity for many years in the trees; 40% better than polypropylene ropes.
  • No rubber insert needed with the controlled stretch, flat braid construction.

Important Notes:

  • Trees compensate for the forces and loads to which they are exposed by allocating resources to build tissue. When static, steel cables are installed, they become part of the whole tree's system and take away the tree's ability to put on new tissue.
  • Cabling of any kind provides only supplemental support (not actual support) to the tree to lengthen its useful life. It does not transform a hazardous tree into a safe tree.
  • Once cabling of any kind is installed in the tree, annual inspection is necessary to ensure that the system is still appropriate for the growing tree.
