Braiding: 8-fold
  
Diameter: 14 mm
  
 Tensile strength: 3,45 t
  
Tensile strength of the system with shock absorber: 3,0 t
  
Ultimate ductile yield: ca. 17 %
  
Service ductile yield (loaded with 20 - 60 %): 3 - 9 %

Product Description:

The new cobra plus 2 t is made of polypropylene monofilaments braided into a hollow rope with a diameter of 14 mm and has a tensile strength of 3.45 t. The 8-fold braiding of 3 yarns allows for an unproblematic insertion of expanding insert and shock absorber. Also the manual preparation of the quick splice is very easy - without any tools. The initial tensile strength of the system is 3.0 t.

The cobra plus 2 t hollow rope has an ultimate ductile yield of 17 % and a service ductile yield between 3 - 9 %.

The polypropylene monofilaments are extremely resistant to environmental influences and therefore have an excellent durability - they lose less than 2 % of their tensile strength per year of service. That is why the cobra plus 2 t system is extremely long-lived and can reliably protect a tree from damage for a period of 12 years.

Product Description:

The new cobra 4 t is made of polypropylene monofilaments braided into a hollow rope with a diameter of 18 mm and has a tensile strength of 5.3 t. The 12-fold braiding of two yarns allows for an unproblematic insertion of expanding insert and shock absorber. Also the manual preparation of the quick splice is very easy - without any tools. The initial tensile strength of the system is 5,4 t.

The cobra 4 t hollow rope has an ultimate ductile yield of 17 % and a service ductile yield between 5 - 9 %.

The polypropylene monofilaments are extremely resistant to environmental influences and therefore have an excellent durability - they lose less than 2 % of their tensile strength per year of service. That is why the cobra 4 t system is extremely long-lived and can reliably protect a tree from damage for a period of 12 years.

Product Description:

The new cobra 8t is made of polypropylene monofilaments braided into a hollow cable with a diameter of 28 mm and has a tensile strength of 10.9 t. The 12-fold braiding of 3 yarns allows for an unproblematic insertion of expanding insert and shock-absorber. Also the manual preparation of the quick splice is very easy - without any tools. The initial tensile strength of the system is 10.0 t.

The cobra 8t cable has a ultimate ductile yield of 17 % and a service ductile yield between 3 - 10 %.

The polypropylene monofilaments are extremely resistant to environmental influences and therefore have an excellent durability - they lose less than 2 % of their tensile strength per year of service. That is why the cobra 8t system is extremely long-lived and can reliably protect a tree from damage for a period of 8 years.

Product Description:

cobra standard that has been successfully installed worldwide since 1993 is made of polypropylene monofilaments braided into a hollow rope with a diameter of 12 mm and has a tensile strength of 2.0 t. The 8-fold braiding of two yarns allows for an unproblematic insertion of expanding insert and shock absorber. Also the manual preparation of the quick splice is very easy - without any tools. The initial tensile strength of the system is 1.8 t.

The cobra standard hollow rope has an ultimate ductile yield of 17 % and a service ductile yield between
2,5 - 10 %

The polypropylene monofilaments are extremely resistant to environmental influences and therefore have an excellent durability - they lose less than 2 % of their tensile strength per year of service. That is why the cobra standard system is extremely long-lived and can reliably protect a tree from damage for a period of 12 years.

We* recommend it for use as dynamic breaking-bracing for branches with a basis diameter of up to 30 cm.

cobra ultrastatic

Technical Specifications:
  
Material: Dyneema, silver coloured
  
Braiding: 12-fold
  
Diameter: 10 mm
  
Tensile strength of the rope: 9,0 t
  
Tensile strength of the system with loops: 7,0 t
  
Ultimate ductile yield : ca. 2 %
  
Service life: 8 years
 
Product Descriptions:

cobra ultrastatic is made of Dyneema braided into a hollow rope with a diameter of 10 mm and has a tensile strength of 9.0 t. The 12-fold braiding of one yarn allows for an unproblematic preparation of the quick splice - without any tools. The initial tensile strength of the system is 7.0 t.

The cobra ultrastatic hollow rope has an ultimate ductile yield of only 2 % and characteristics that are similar to those of a steel rope. With only 46 g per meter, however, cobra ultrastatic has an enormous weight advantage.

cobra ultrastatic was specifically developed for use as static breaking-bracing or as load/support-bracing and is also suitable as replacement for old steel-rope bracings.

According to 'ZTV Baumpflege 2006' (German Tree Care Standard), cobra ultrastatic is to be classified as a 4-t system and therefore can also be used as static breaking-bracing or as load/support-bracing for branches/stems with a diameter of up to 40 cm.
