The spare rope for HK calf pullers does not absorb blood and does not become rigid. Material: PPMF. The rope is made as a 3-strand twisted pair. PPMF absorbs a maximum of 0.1% moisture compared to 10% for the previously used polyamide. This means it does not shrink when drying, becomes rigid less quickly, and lasts longer. The rope also absorbs hardly any blood and stays hygienically white. Colour: white Length: 80 cm
