In contrary to usual plastic ropes, Kevlar stretches only very little under the influence of wetness, heat and cold. Additionally, the strength compared to the diameter is very high and the weight very low.
We deliver Kevlar ropes in the following versions:

| K2 | 2.5 mm | 210daN | 0.4kg (0.88lbs.) | Polyester |
| K3 | 3.5 mm | 500daN | 0.85kg (1.87lbs.) | Polyester |
| K4 | 5.0 mm | 800daN | 1.7kg (3.74lbs.) | Polyester |
