General information about the COBRA bond system:
Experience and quality:
Cobra products are designed for dynamic and static securing of tree crowns.
They have been used worldwide since 1994. Experienced arborists appreciate the durability of the fibers of the dynamic bonds,
which are not susceptible to damage during installation.Efficiency and Economy:
Expansion Inserts: Thanks to expansion inserts, the rope is in contact with the trunk
and branches significantly expanded and thus does not cut into the bark, does not damage the cambium and therefore does not risk failure
At the installation site during the years following installation.
Shock Absorbers = Shock Aborbers: They are made of a slippery rubber compound and can easily be inserted into the center of the hollow rope.
Prevents the so-called Karate effect. In the case of wind, when there are fluctuations of trunks and skeletal branches, it is necessary,
so that the dynamic bond does not act as a "steel anchor" that disrupts the natural elasticity.
In order not to break at the installation site at this critical moment, it is inserted in the middle of the binding rope
Shock absorber, thus reliably providing the tree with sufficient freedom of movement to preserve the formation of reaction wood.
The shock absorbers slow down the opposing movements of the swingarms and reduce the final shock force by 20%.Packaging:
Cobra crown locking systems are supplied in functional impregnated water repellent cardboard with handles.
Advantages of the COBRA system:
Material quality
Simple and user-friendly criteria for the correct selection of the type of binding according to the diameter of the skeletal branches
Very low weight of polypropylene ropes
High abrasion resistance of ropes
