Adjustable cow’s tails allow one to change the length of the cow’s tail easily.
The problem with a standard cow’s tail is that if one falls from above the anchor, the resulting fall factor can be quite high. This is especially true for via ferrata, where fall factors of 5 or 10 or even more are possible. Dynamic cow’s tails incorporate a shock absorber of some form so that the forces generated in such falls are greatly reduced, hopefully to within human tolerance. The ones listed here are commercially produced, and except for the gear4rocks and Kong Slyde, include their own sling rope. These should only be used in the situations recommended by the manufacturer. Most of the anchor brakes can also be used to make dynamic cow’s tails, if the manufacturer endorses such use.
The weights in the following table are for the entire kit, unless otherwise noted. The dimensions are for the brake plate.
