The Strend Pro Premium rope is made of polypropylene and is used for emergency towing of motor vehicles. The rope is designed for towing vehicles weighing up to 2 tons, with a length of 5 m. The self-locking rope is not equipped with hooks or carabiners, thus preventing any scratching of the vehicle body during use. The towing rope includes a red flag measuring 30x30 cm.
The diameter of our ropes is measured according to the European standard EN 2307, which specifies the exact measurement procedure. However, it is important to know that the resulting diameter of the rope may have a certain tolerance. This deviation depends on the construction of the rope (e.g., type of braid, number of strands) and the material from which the rope is made. Special attention should be paid to ropes made from natural fibers, such as jute or sisal. For these ropes, the diameter may vary between individual production batches, because natural yarns have inherent differences in thickness, elasticity, and absorbency. These deviations are not a defect but a normal property of natural materials.
Approximate rope diameter tolerance
Type of rope | Material | Construction | Diameter tolerance |
---|---|---|---|
Natural rope | Jute, sisal | 3–4 strand | ± 12 % |
Synthetic twisted and braided ropes | PP, PPV, PES, PA | 3, 4, 8, 16, 24, 32, 40, 44, 48 strand | ± 8 % |
Note: For natural ropes, the tolerance may be higher due to the influence of moisture, storage, and the natural variability of fibers.
When selecting a rope, we recommend taking this tolerance into account, especially if the rope diameter is crucial for its use (e.g., in combination with fittings, pulleys, or other technical elements).
