[Features] ● Color-coded red and green so that 3m can be separated when using the intermediary rope. ● Safe work can be done by visualization. ●Because the raw yarn is colored when it is manufactured, it is less likely to cause color unevenness, color fading, or color transfer like piece-dyeing. ●The hook and rope are integrated, and a reinforcing metal fitting is inserted between them to prevent them from tearing apart.
