Cobra bracing is a complete cabling concept that incorporates a shock absorbing system. The unique patented system is entirely external, all synthetic, and easy to use; you need only to know a simple rope splice technique. This system can be crafted on site. Cables features a wide insert that spreads upon contact with the tree reducing pressure. Expansion inserts rest around the limb broadening the support. Anti-friction sleeves eliminate abrasion and shock absorbers allow for free movement, reducing the possibility of the "karate chop" effect during high winds. The "growth loop" allows for tree growth without girdling and can be inspected from the ground. No drilling is required, for healthier wood.2 ton strength. 33 meters Cobra rope, 8 meters anti-friction hose, 10 expansion inserts, 5 shock absorbers, 10 endcaps and lubricant.
