The webbing line of autobelay, to which the climber is attached before the ascending, is constantly under tension. In this regard, for a time when the autobelay is not used, the webbing line must be locked so that it does not retract independently upward into the device at altitude. A good solution to this problem is the kerchief, which has an opening on one of the edges to attach the carbine to the webbing line. On the wide side, the scarf is firmly attached to the floor or to the climbing wall. Thus, when the autobelay is not used, the webbing line is attached to the kerchief that is in the raised state. When the climber climbs, the kerchief falls on the floor, not interfering with the ascent. At the same time, the kerchief also serves as a signal function for climbers on top.
