Important Notice:
Accessory cords are frequently used with prusiking. Because the sheath of the cords is relatively weak, it has to be continually checked whether the sling is not getting damaged - worn-through - due to its continual displacement along the rope. Any sign of damage means that the prusiking knot has to be re-fastened in such a way as to ensure that the non-disturbed surface of the rope gets into contact with the rope at all times. If the core is sneaking out of the sheath, the disturbed portion of the cord has to be cut off, or the cord should be preferably discarded.
As well as the ropes, the material of the accessory cords is subject to aging. We recommended that the cord be replaced after 5 years of service.
