40 m reel
Material: Polypropylene monofil, blackened
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 %
Ageing: 2 - 3 % per year
Service life: 12 years
The cobra 2t is made of polypropylene monofilaments braided into a hollow cable with a diameter of 14 mm and has a tensile strength of 3.45 t. The 8-fold braiding of three 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 2t cable has a 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 2 - 3 % of their tensile strength per year of service. That is why the cobra 2t system is extremely long-lived and can reliably protect a tree from damage for a period of 12 years.
